Hmm, I guess that’s changed since I built our deployment!

I’ll update our deployment to pull the latest.

I see you’ve got composer.phar in .gitignore, so it can go in 
/srv/ixpmanager without a problem.

Actually, I see what’s happened now!

Looking at the list of packages for which I have an 8.1 version 
installed, most of them are specified in the deployment as ‘php-xxx’ 
instead of ‘php8.0-xxx’. (The other few are presumably dependencies 
of those, eg: php8.1-common).

This must have been historic and when I converted from ubuntu stock PHP 
to the PPA for the 6.x update, it must have worked fine because the 
latest was 8.0 anyway. At some point recently, those package aliases 
must have changed to point to 8.1 versions, so when I did the 
dist-upgrade, it’s installed the 8.1 versions.

Thankfully our production box hasn’t got those, just the development 
machine, so this is an easy fix after all!

Thanks,

Ian
