PHP7-ubuntu sessionclean searches for "php5" named binary

[Amael]

I just upgraded from ubuntu 15.10 to ubuntu 16.04 and my root mail is spammed by an error of php tool "sessionclean". This tool is still installed in /usr/lib/php5/sessionclean, and searches for the php binary under the name "php5".

The php-cli version installed is php7.0-cli, and the php-common ist still in php5-common. I have the php-common metapackage, shouldn't it have upgraded to a php7-common or something like that ?

I fixed the issue by manually editing "/usr/lib/php5/sessionclean" file and use "php" instead of "php5".

Did you fully uninstalled and purged php5* packages, e.g. doing `apt-get purge php5-common`.

[Robie Basak (racb)]

According to http://packages.ubuntu.com/xenial/all/php-common/filelist php-defaults provides sessionclean in /usr/lib/php/sessionclean. Perhaps this is an upgrade related bug? What version of the php-common package do you have installed after the upgrade? And what does "dpkg -S /usr/lib/php5/sessionclean" say?

[Amael (amael)]

Hello, i did not install php7 myself so i did no manual uninstall neither.
Looks indeed like an upgrade problem.

I have indeed both sessionclean binaries, provided both by php-common package :

amael@amserv:~$ dpkg -S /usr/lib/php/sessionclean
php-common: /usr/lib/php/sessionclean

amael@amserv:~$ dpkg -S /usr/lib/php5/sessionclean
php5-common: /usr/lib/php5/sessionclean

amael@amserv:~$ ls -al /usr/lib/php5/sessionclean /usr/lib/php/sessionclean
-rwxr-xr-x 1 root root 1,5K mai 8 10:07 /usr/lib/php5/sessionclean*
-rwxr-xr-x 1 root root 2,9K mars 1 16:28 /usr/lib/php/sessionclean*
amael@amserv:~$

I just tried an upgrade from Wily to Xenial. Using do-release-upgrade, php5-common was correctly removed as expected.

Please can you explain how you upgraded to Xenial? I think we need exact steps to reproduce to make any progress now. Please change the bug status back to New once you have this.

[Amael (amael)]

Hello, I upgraded with do-release-upgrade as well. My system is kind of old (June 26th of 2011) with different updates since (not all in a row, I skipped one or two).

I just checked what packages were flagged to "manually installed", this is probably the reason :
amael@amserv:~/Bureau/photos$ comm -23 <(apt-mark showmanual | sort -u) <(gzip -dc /var/log/installer/initial-status.gz | sed -n 's/^Package: //p' | sort -u) | grep php
php5-mysql
php-codesniffer
phpmyadmin
phpunit

And automatically installed :
amael@amserv:~/Bureau/photos$ comm -23 <(apt-mark showauto | sort -u) <(gzip -dc /var/log/installer/initial-status.gz | sed -n 's/^Package: //p' | sort -u) | grep php

Unflagging the php5-mysql as manually installed removes the php5-common package :
amael@amserv:~/Bureau/photos$ sudo aptitude markauto php5-mysql
Les paquets suivants seront ENLEVÉS :
  php5-common{u} php5-mysql{u}

@martin suc

Please do not change the bug status without an explanation.

As I requested in comment 5, this bug still needs exact steps to reproduce in order to make any progress.

[Nish Aravamudan (nacc)]

So I think I see a potential issue, based upon #c6.

In a trusty lxd, I did:

# apt install php5

The result of the 'manually installed packages' is:

# apt-mark showmanual | grep php
php5

Note that specifically, php5-common is not marked as manually installed. So I'm guessing, as Amael mentioned in #c6, that php5-mysql was installed after the fact, manually (as opposed to as a dependency resolution), and thus was kept over the release upgrade (I believe this is normal/expected, so things don't unexpectedly break). I wonder if Robie, during your test, you just installed php5 (as opposed to some php5- package like php5-mysql) before release upgrading?

I'm not sure what the right solution is here, as Amael noted, I would suggest, after completing the upgrade, to ensure all php5* packages are removed (apt remove php5*, I think, would do it -- without purging the configuration so you can migrate it).

I think the primary issue here, as well, is that php7.0-mysql doesn't really replace php5-mysql (as the extension was deprecated in php5 and removed in php7: https://wiki.php.net/rfc/mysql_deprecation), so perhaps for that specific package there is no transition path (and that is part of the migration to PHP7.0 generally).
