Description of my issue

Since a few weeks, all system upgrade always finish with the following messages

x upgraded, x newly installed, 0 to remove and 18 not upgraded.

(where the 2 first x refer to some other successfully upgraded).

But now since 10 days, a new message has appeared about 16 php related packages which are kept back. As an exemple, here is the full output of my commands no later than 5 minutes ago:

$ sudo apt update

0 upgraded, 0 newly installed, 0 to remove and 18 not upgraded.

From other messages on this forum, I tried to run the following command, which all return nothing:

sudo apt-mark showhold
sudo dpkg --list | grep ^hi

I’m not at all a Debian expert, thus I really don’t know what to do more to understand what is going on (I’m a bit lost between apt, apt-mark, apt-get, aptitude, dpkg :/). I don’t understand why those php module refuse to upgrade, nor what are the 2 other unnamed packages (18-16). Any help will be welcome to unlock the situation. Thank you very much.

After some tests by myself, I succeed to remove the php-5… packages, which were still there because my yunohost install is quiet old (back to yh 3…) and they never have been automatically removed.

Thus now I’m down to 4 php package, but still have 2 mysterious not upgradable packages:

The following packages have been kept back:
  php7.3-igbinary php7.3-redis php8.1-igbinary php8.1-redis
0 upgraded, 0 newly installed, 0 to remove and 6 not upgraded.

From what I understood in aptitude, all my PHP app are still using php7.3, but nextcloud depends on php-redis and php-igbinary (note the absence of version in the named package), which are aliases for php8.1-igbinary php8.1-redis. And it seems that it causes some kind of deadlock on versioning between related 7.3 and 8.1 packages.

But all that still does not explain how I could find the missing 2 not upgradable packages :confused:

Thank you in advance for any help.
