Yes, as TRon said, if you use your distro's version of Lazarus, its probably out of date.
Your distro is based on Debian Bookworm, it has Lazarus 2.2.6 so that all makes sense. While using a later Lazarus would be a good idea (as TRon suggested) maybe you want work out why your Lazarus 2.2.6 is not working ? Lots and lots of installs work as expected. I'd very much doubt Aqurius makes any changes to Lazarus !
Did you look to see if /usr/lib/lazarus/2.2.6/lazarus is there ? Generally, an install like this (in root space) must be started with startlazarus rather than lazarus, so maybe your error came from startlazarus ?
$> ls -l /usr/lib/lazarus/2.2.6/lazarus
Did you start from the command line or using a menu ? If menu, then you will be hitting lazarus.desktop and it should have the right command. Such commands go through debian's "alternatives" system, far too complicated and maybe broken by Aqurius ? Who knows ? Worth trying from the command line, might see some hint of where the problem is, I'd try -
$> startlazarus
and
$> /usr/lib/lazarus/2.2.6/startlazarus
If you decide to abandon Lazarus 2.2.6 (and thats a good idea) make sure you remove all traces of your failed Lazarus install before starting a new model. I always suggest installing Lazarus from source into user space, instructions

Let us know how you go.
