[ixpmanager] PHP 8.1 released - may cause some issues with apt upgrade

[Barry O'Donovan (INEX)]

Hi all,

PHP 8.1 was released in the last few days. When it comes to updates, 
this may cause an issue - e.g.:

root at ixpmanager:/srv/ixpmanager# apt update
...
root at ixpmanager:/srv/ixpmanager# apt upgrade
...
The following NEW packages will be installed:
   distro-info libllvm12 php8.1-common php8.1-ds php8.1-igbinary 
php8.1-memcache ...


While IXP Manager should work fine with 8.1, we haven't tested it yet. 
But also, you don't want a mixed 8.0 / 8.1 environment on your system.

The reason the above happens is because the installation instructions I 
did up had some PHP packages as version specific (i.e. php8.0-xxx) but 
others as aliases (php-xxx) - it's the aliases that are causing the 
above issue.

You can solve as follows:

dpkg -r php-ds php-igbinary php-memcache php-memcached php-msgpack 
php-rrd php-yaml

The above should be a no-op as these are aliases. You then need to 
explicitly install the version specific ones:

apt install php8.0-common php8.0-ds php8.0-igbinary php8.0-memcache 
php8.0-memcached php8.0-msgpack php8.0-rrd php8.0-yaml

The above may or may not install packages - it depends on whether the 
ones you have installed are up to date or not. If they are up to date, 
then the above just marks them as explicitly installed (rather than 
installed because of the php-xxx alias). If they are not up to date, 
they will be upgraded. Either result is fine.

You'll need to sanity check each step as you do this to ensure the 
results are sane.

The desired result is that dpkg -l | grep php8.1 returns no packages.

The installation documentation and automated installers have all been 
updated to use php8.0-xxx specific packages.

Thanks,
  - Barry
