This might be one basic question.
but I wanted to download packages of specific debian version from debian mirror.
e.g I wanted to download debian 9.11 packages but when I checked on debian mirror(http://ftp.debian.com/debian/dists/)
I could see only debian 9.12 entry and no entry of 9.11
screenshot of debian mirror
I know debian must archive these packages and mirror somewhere else but I am currently not able to find it
Once a developer told that he used jigdo images to get the archived mirror. But I am not able to extract debian mirror url from jigdo images
Thanks
I after searching over the internet, I got the solution.
I found mirror url from jidgo image uploaded by debian.
I downloaded jidgo image of debian 9.11 from here
https://cdimage.debian.org/cdimage/archive/9.11.0/amd64/iso-cd/
and used zcat command on .jidgo file and found mirror at the end of the file
the mirror was something like this

When updating your system on archlinux with pacman -Suy, pacman gets package databases from somewhere and then downloads packages from mirrors according to versions specified in these databases.
I know these databases are in /var/lib/pacman/sync/. My question is, where does pacman get them from?
The db files also come from the package mirrors specified in /etc/pacman.d/mirrorlist.
For example in this core repo:
...
core.db 136.6 KiB 2022-Mar-05 12:53
core.db.tar.gz 136.6 KiB 2022-Mar-05 12:53
...
The wiki also mentions what to do if you get an error:
Failed retrieving file 'core.db' from mirror
If you receive this error message with correct mirrors, try setting a different name server.
I have Postgres-XL 10 installed with geos-3.9.1 and postgis-3.1.1 on my Amazon Linux 2 machine. My cluster is running and working flawlessly but I am having troubles with getting postgis installed into the database. I've built and installed everything from source.
The error I'm getting when I run CREATE EXTENSION postgis; is:
ERROR: could not load library "/usr/local/pgsql/lib/postgis-3.so": libgeos_c.so.1: cannot open shared object file: No such file or directory
Using solutions from other posts online, I have tried:
Running sudo ldconfig
Using the --enable-shared option when installing geos and postgis
Ensured /usr/local/lib is in the LD_LIBRARY_PATH environment variable and I also added /usr/local/pgsql/lib to LD_LIBRARY_PATH
None of these solutions worked. I can't install PostGIS or Geos using yum because it will install postgresql 12 which conflicts with my version of postgresql which is a custom one for Postgres-XL.
Is there anything else I can try to solve this error? Any help is appreciated.
Thanks.
It looks like you might need to downgrade. Postgres-XL is only supporting 2.0.x versions of postgis right now. At least according to their docs.
https://www.postgres-xl.org/faq/
Q. Is PostGIS supported?
Yes, PostGIS can be added to Postgres-XL. It has been tested with PostGIS 2.0.
The official website makes it pretty clear that there is no support for kenlm in Windows. There is a Windows tag at the github repository but it seems to be maintained by few random contributors then and there.
How to set up kenlm for Windows then?
The new DeepSpeech PlayBook also includes instructions for setting up a Docker image and running training from within a Docker container. If you have Docker on Windows, this might be another solution.
The information for building a new Scorer is still in a PR, but may also be useful.
The solution is to use Ubuntu in Windows through Windows Subsystem for Linux
Get WSL for Windows
From your ubuntu bash navigate to the folder where you want to do the setup. You can access the Windows file system from the /mnt/c/ folder, which you can find at the root directory.
From there simply follow the official instructions, that is clone the git repo, and run cmake .. & make -j2 in order to build the project (after first making the necessary installations in your Ubuntu system).
Obviously, you must train the models or scorers using the Linux bash. You can also use these models from Windows using the kenlm python library.
E.g.
The two steps to build a scorer for the deepspeech-model as described here should be executed from your Ubuntu system. But after you have the scorer you should be able to run the command
deepspeech --model deepspeech-0.9.3-models.pbmm --scorer kenlm.scorer --audio audio.wav
from Windows. However, once you have WSL there's no need to do this work from Windows. Things will work nicely #your Ubuntu system.
I've faced the same problem and solved it by building kenlm wheel from Cygwin terminal as home page advices (pip wheel pypi-kenlm).
I've also uploaded wheel to pypi called kenlm-cygwin, but it's only python3.7.
I want to run a tiles server with OSM data
i want to install mod_tile so i followed the mod_tile setup
But when i do the
./configure
It says
checking for getloadavg... yes
checking for apxs... no
checking for apxs2... no
checking for /opt/local/apache2/bin/apxs... no
configure: error: Could not find apxs on the path.
any idea what went wrong?
According to the Internets you need to install apache2-dev (previously known as apache2-devel). The apx binary should then be located under /usr/bin/apxs2 or /usr/sbin/apxs2.
Note: For building a tile server you should follow the guide on switch2osm.
For Ubuntu
sudo apt-get install apache2-devel
For RedHat & CentOs
yum install httpd-devel
SUSE has removed the SDK ISO from the area where you download the server ISO.

I consider their page as very complicated and not logical so play a bit around but you find it in the end.

I want to install FastStart on my laptop (cloud-in-a-box),
My current operating system is Windows 7
So, I burned the FastSTART on a DVD
It is recommended to install linux before or the DVD wil install both the system Centos and FastSTART?
thank you
The DVD will install both CentOS and Eucalyptus. The installation is quite straightforward, but understand that installing a new Operating System, such as CentOS means that you will lose your Windows 7 installation. Prior to installing, please make backups of everything you may need. Have a look here for the instructions to install Eucalyptus from the faststart iso.
You should also look at the YouTube video that is produced by Eucalyptus.

Basically it will wipe out the existing operating system and data on your machine and put CentOS on it. Don't do this on your main machine. Do it on another machine.
