Dear Martin,
Hopefully we can set some reasonable limits and keep the page up to date. But to make this job easier, we should try and see if we can set up some automatic support scripts that pull in a summary of the different distros and their versions of key dependencies.
For Debian there are online lists with all packages and versions, e.g.
https://packages.debian.org/stable/allpackages?format=txt.gz https://packages.debian.org/oldstable/allpackages?format=txt.gz https://packages.debian.org/testing/allpackages?format=txt.gz https://packages.debian.org/jessie/allpackages?format=txt.gz
(goto https://packages.debian.org/stable/, select a version at the top and click at the end on "(compact compressed textlist)")
For Ubuntu the lists are e.g.
https://packages.ubuntu.com/de/xenial/allpackages?format=txt.gz https://packages.ubuntu.com/de/yakkety/allpackages?format=txt.gz https://packages.ubuntu.com/de/zesty/allpackages?format=txt.gz
(goto https://packages.ubuntu.com/en/, click on a Ubuntu version and at the end on "(compact compressed textlist)")
Mint has it as HTML:
http://packages.linuxmint.com/list.php?release=Sonya Should be easy to convert with XSLT.
I guess there are similar lists for the other major distros.
It should take only a few lines of Python to fetch and check these.
What are the relevant distros?
Best regards,
Michael
