I have updated packages many times after 12.1 release, but I still have 12.0 in debian_version file. I tried to install today printer drivers but it couldn’t get the latest libcupsimage2 2.4.2-3 library on the server although there is 2.4.2-5 already.
How to fix the version? Is it possible that it breaks cupsimage installation?
So 12.1 is out but have you upgraded any of your packages yet? The
/etc/debian_versionfile comes from thebase-filespackage. On my up to date system, it’s showing12.1in the file and the package version is12.4+deb12u1as I can see fromdpkg -l base-files.Make sure to do an
apt updateand then do anapt upgrade -sto do a dry-run to see what packages would be upgraded. I’m guessing thebase-filespackage hasn’t been updated.
