I have installed opam 2.1.0 on a Linux Virtualbox VM. When I try opam init, I get the following error:
<><> Fetching repository information ><><><><><><><><><><><><><><><><><><><><><>
[ERROR] Could not update repository "default": OpamDownload.Download_fail(_, "Curl

[ERROR] Initial download of repository failed.
Running with --disable-sandboxing doesn't help. I know that its a problem creating/writing to /tmp/opam-... directory because if I replace that with my current directory or home directory the command by itself runs fine. It also runs fine with /tmp/opam-... if I use the --create-dirs option in curl but I don't have any way of getting opam init to use that option. Any ideas?
thanks
Update
The reason opam init failed for me was because curl was installed with snap on my system. This exactly what is going on with your VM.
Try to run opam init -verbose and that could reveal more about why you ran into an error.
In my case I needed to install other things with opam and it kept failing every time. So snap uninstall curl and then sudo apt install curl fixed things. (Was only able to figure this out with help from my professor)
Workaround
I ran into the same issue and I found a workaround on the OCaml forum: here. (Credits to UnixJunkie)
You can run:
opam init github git+https://github.com/ocaml/opam-repository.git
This should avoid the certificate issues. This worked for me.
I tried to fix the certificate issues using this answer as well. You could try doing that, but it seems complicated when the workaround is to simply point it to the github repo directly.
This question is similar to this one.

I was trying to create react app but again and again npm update check failed issue was comming so i tried a lot of solutions to fix this error but none of them worked.And i am using a windows 10 pc
First of all Reinstall NodeJS, If problem is still there then follow the following steps:
Following is the answer from github
Fix for windows, I got this message :
npm update check failed Try running with sudo or get access to the
local update config store via sudo chown -R $USER:$(id -gn $USER)
C:\Users.config
so I went on to C:\Users.config and deleted the
"configstore" folder. once I done this, next time a ran npm start, the
folder was re-generated, and error stopped

Can I get a tip for installing on rasp buster? Im hung up on the install directions to check the status of the rabbitMQ server. Traceback of bash console:
(volttron) pi#raspberry:~/Desktop/volttron $ echo 'export RABBITMQ_HOME=$HOME/rabbitmq_server/rabbitmq_server-3.7.7'|sudo tee --append ~/.bashrc
export RABBITMQ_HOME=$HOME/rabbitmq_server/rabbitmq_server-3.7.7
(volttron) pi#raspberry:~/Desktop/volttron $ source ~/.bashrc
pi#raspberry:~/Desktop/volttron $ RABBITMQ_HOME/sbin/rabbitmqctl status
bash: RABBITMQ_HOME/sbin/rabbitmqctl: No such file or directory
There are a few tracebacks earlier on the installation...
If it makes a difference or not here is the entire bash console process. The git gist link I just created the name install.py even though its just bash commands copied pasted per install directions...
`pi#raspberry:~/Desktop $ git clone https://github.com/VOLTTRON/volttron --branch releases/7.x`
It looks like there are a couple of different issues going on here:
The issue you quote above (RABBITMQ_HOME/sbin/rabbitmqctl: No such file or directory) is that your shell isn't finding the rabbitmqctl command. It looks like you added the RABBITMQ_HOME environment variable to your .bashrc, but used the string RABBITMQ_HOME instead of the variable expansion $RABBITMQ_HOME when you tried to run the command. Try running it as $RABBITMQ_HOME/sbin/rabbitmqctl status instead.
The rabbitmqctl status command will check the status of the rabbitmq application, but I don't think you've done anything to start it yet (that happens when you bootstrap the platform and/or start the platform configured to use the RMQ broker)
I think that the traces earlier in the installation process are problematic (appears to be the same error hit two different ways), but you just haven't run into them yet. I haven't seen any issues building gevent on the RPi 4 with buster (though it is pretty slow), but the ctypes error makes me wonder if there's an issue with the underlying c library it is trying to build on top of. I did notice that you're getting amd64 erlang packages, are you running Raspbian on an x86 processor? (if so this isn't a permutation we've tried and you may be hitting some package compatibility edge case we haven't seen)
One thing to try is to manually install cython into your virtualenvironment and then try running the bootstrap script again with the virtualenvironment activated. You could also try and pip install gevent==20.6.1 directly in that virtualenvironment (this is what the bootstrap script was doing at the failure point). VOLTTRON depends on gevent, so if that isn't installing the platform won't be able to run.
I've been trying to install MacPorts on a new Mac Pro with a fresh, fully updated Yosemite OS. The installer hangs on 'Running package scripts'. So I tried to build it from source. That works, with the installer stating:
Congratulations, you have successfully installed the MacPorts system.
However, it seems unusable. When I do sudo port install apache2 I get the message:
Error: Port apache2 not found
Simply trying to do a 'self update' (as root):
sh-3.2# port -d selfupdate
DEBUG: MacPorts sources location: /opt/local/var/macports/sources/rsync.macports.org/release/tarballs
---> Updating MacPorts base sources using rsync
receiving file list ... done
base.tar
...and then nothing... I've waited for half an hour, but it won't go any further. I can't find any logs either.
Again: there's nothing special about my setup, it's out-of-the-box Yosemite, only updated through the App store and, of course, I've installed Xcode with command line utilities and formally accepted the license, as is required according to the MacPorts site.
I've also tried uninstalling it, using the instructions from the MacPorts site, and reinstalling. But it does not make a difference.
I've read quite a few forum posts, but I can't find any post relating a problem like this. I hope someone can shed some light on this.
The installer hangs running package scripts because the last statement in these package scripts is exactly this "sudo port selfupdate" that you've been running manually afterwards.
Because this step did never run, your MacPorts installation lacks knowledge about the apache2 port (which is exactly why the installer runs selfupdate to give you a full-featured installation).
Unfortunately Apple's infrastructure (rsync.macports.org) seems to have connectivity problems at the moment, which is causing problems for quite a few people. You can try using one of the mirrors as outlined at https://trac.macports.org/wiki/Mirrors.
I am trying to install CKAN on my local computer using Ubuntu 14.04 LTS.
I followed the instructions for installing from source found here and I try to check if solr is running by visiting http://localhost:8983/solr/.
I can see that Jetty is running because when I visit http://localhost:8983 I see that it is up.
I added the jdk as follows:
JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk-amd64
I am getting a 500 error when i try to open the solr page:
HTTP ERROR 500
Problem accessing /solr/index.jsp. Reason:
JSP support not configured
Powered by Jetty://
Any ideas? Should I redo the whole thing from the start?
Edit/Update
I just couldn't do anything with this installation. The bigger problem was that installation files were meshed up! I tried to install tomcat/solr instead of jetty/solr and things went sour. So I just created a VM and did a fresh install there. For anyone interested I did a tomcat/solr installation following this and a CKAN installation following this (with out of course the solr instructions). Also, for some reason the CKAN installation has commented out the solr URL, so even if it is right, I had to delete the comment.
A fix has been documented by #mstantoncook here [2939] & [1651] How to solr-jetty JSP support
Note the last comment, sudo service jetty restart
It's a Jetty BUG on Ubuntu 14.04!
There is nothing wrong with Ckan itself.
Actually, there is a bug in the libjetty-extra-java package (version 6.1.26 and newer) in Ubuntu 14.04. The bug was introduced after Jetty (in Ubuntu) has changed it's dependences from libtomcat6-java to libtomcat7-java.
You can get more info about this bug in Ubuntu Launchpad: Bug #1508562 "Broken symlinks for JSP support in libjetty-extra-java version 6.1.26-1ubuntu1.1".
The bug is already fixed on Debian, and I'm hope it will be solved in Ubuntu 14.04 soon.
There are workarounds that may work for your case
I proposed some workarounds in this bug report, and since they can be useful for the Ckan users, I'll also replicate them here.
All of them consist on use both jetty and libtomcat7-java, but adding/replacing some classes (code ported from libtomcat6, in put in the jsp-2.1-6.0.2.jar file) to the Jetty classpath.
I don't know if they have some problem. Use them at your own risk!
Workaround 1 - Install the fix package proposed by vshn
I found this workaround here: https://github.com/ckan/ckan/pull/2966
In short:
wget https://launchpad.net/~vshn/+archive/ubuntu/solr/+files/solr-jetty-jsp-fix_1.0.2_all.deb
dpkg -i solr-jetty-jsp-fix_1.0.2_all.deb
service jetty restart
This will install a JSP jar that works (the file will be named jsp-2.1-6.0.2.jar, but it contains classes ported from libtomcat6).
Workaround 2 - Manually install the JSP jar
Download the same JAR file that the DEB package above would install.
wget https://bugs.launchpad.net/ubuntu/+source/jetty/+bug/1508562/+attachment/4785985/+files/jsp-2.1-6.0.2.jar
Now, move it to a proper location inside the Jetty config dir. I did it this way:
mkdir /etc/jetty/extra-jars
mv jsp-2.1-6.0.2.jar /etc/jetty/extra-jars
And add a line like this one in the Jetty start.config file:
echo "/etc/jetty/extra-jars/jsp-2.1-6.0.2.jar" >> /etc/jetty/start.config
And:
service jetty restart
Correct solution
The correct solution is to wait for the Ubuntu Team solution. However, while waiting for this fix, you can use any of the previous workarounds (I prefer the last one).
I hope they help you!
Try this steps:
sudo mv jsp-2.1-6.0.2.jar /usr/share/jetty/lib/.
change own:
sudo chown root:root /usr/share/jetty/lib/jsp-2.1-6.0.2.jar
finally restart jetty:
sudo service jetty restart
I followed this steps and now I can see localhost:8983/solr and localhost/solr/admin
In Ubuntu 14.04 this can be fixed with:
cd /tmp
wget https://launchpad.net/~vshn/+archive/ubuntu/solr/+files/solr-jetty-jsp-fix_1.0.2_all.deb
sudo dpkg -i solr-jetty-jsp-fix_1.0.2_all.deb
sudo service jetty restart
Following http://docs.ckan.org/en/ckan-1.6/solr-setup.html#single-solr-instance
(this one a bit old, but worked perfect for me )
You will have to edit /etc/profile and add this line to the end such as this to the end (adjusting the path for your machine’s jdk install:
JAVA_HOME=/usr/lib/jvm/java-6-openjdk-amd64/ (or other version)
then
export JAVA_HOME
sudo service jetty start
I am trying to use the static binary of wkhtmltopdf on Ubuntu server 10.0.4. The reason for is that it apparently has a built in modified QT that will allow me to run wkhtmltopdf without an X Server.
Result:
Once installed (see steps below), when I execute wkhtmltopdf in the terminal, it does not fire up... just returns me to the prompt - like it ran and did something, no error but no output:
:/usr/bin$ wkhtmltopdf
:/usr/bin$
Same behavior if I put args:
:/usr/bin$ wkhtmltopdf http://www.google.com test.pdf
:/usr/bin$
Am I doing something wrong --- my understanding that the static binary should just fire up. Perhaps missing some dependency? Is there a way to get some verbose output?
These are the steps I have followed:
In /usr/bin:
1) Confirmed that the existing (non-static) wkhtmltopdf resides there and that it executes. When I execute it with no args I get the help/about output from the app.
2) Moved the existing wkhtmltopdf out of the directory (renamed it)
3) Get the static binary: sudo curl -C - -O http:
//wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.9.9-static-i386.tar.bz2
4) Untar: tar xvjf wkhtmltopdf-0.9.9-static-i386.tar.bz2
5) Rename: mv wkhtmltopdf-i386 wkthtmltopdf
6) Get (apparently) necessary packages: sudo apt-get install openssl build-essential xorg libssl-dev
I was having the same problem. I removed the existing wkhtmltopdf and followed the steps below and the installation worked.
First, installing dependencies
sudo aptitude install openssl build-essential xorg libssl-dev
for 64-bit OS
wget http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.9.2-static-amd64.tar.bz2
tar xvjf wkhtmltopdf-0.9.2-static-amd64.tar.bz2
chown root:root wkhtmltopdf-amd64
mv wkhtmltopdf-amd64 /usr/bin/wkhtmltopdf
The only difference is that I put it in /usr/local/bin/wkhtmltopdf.
I hope this helps!
Following deb's answer got it working for me on Ubuntu 10.04 64bit - thanks!
Although rather than downloading 0.9.2 as per deb's instructions, I would suggest people download the latest version by:
Go to http://code.google.com/p/wkhtmltopdf/downloads/list
Download the latest version of wkhtmltopdf-[version number]-static-amd64.tar.bz2
At this time, the latest 64bit is http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.11.0_rc1-static-amd64.tar.bz2.
In my debian server trying to run wkhtmltopdf-i386 lead to same blank prompt.
Non-static (with non-patched QT) version of wkhtmltopdf installed with "aptitude install wkhtmltopdf" is worked.
Problem solved by switching to wkhtmltopdf-amd64, server was a 64 bit and i missed it.
After that, wkhtmltopdf-amd64 says 'libxrender shared library not found', this problem was solved by "aptitude install xorg"
0.11.0_rc1 seems to be buggy.
It keeps throwing the error "Cannot create a QPixmap when no GUI is being used".
Reverting to 0.9.9 worked for me.
