I have told you twice now where the official installs are. I have told you once that the debian (and other linux) repositories are notoriously problematic. Those aren't official.
Yes, that's right. You told me three ways to install Lazarus and I tried them all.
fpcupdeluxe creates a working IDE, but when I try to add a module it's broken again and doesn't start at all.
The setup from
https://www.lazarus-ide.org/index.php?page=downloads weems to work, but has a non sizeable main window.
When I press F1 on e.g. TForm it takes 10 to 20 secods to display the help while writing one or more of the following message to the console: LHelpControl: WaitForMsgResponse: hit timeout (10 seconds)
The setup.sh from
https://www.getlazarus.org/setup/ wants to have 700 MB (expanded) of gtk and other dependencies (While the former only wanted about 100 MB) and insists to be installed under my personal directory; /home/lazarus/IDE is not accepted.
After long downloads and compiling with tons of warnings and errors (e.g. cannot execute /home/paul/FreePascal/lazarus/ide (because tne execute bit isn't set)) I got - nothing. Cannot even find an executable of the ide.
These three different approaches are totally confusing to me
On the second start of the resulting lazarus-ide (after switching the language to English) I got a message stating that it found a IDE configuration that was previously used by another installation (I deleted ~/.lazarus before installing this one)
So the second approach is the best of them, but none of them results in a really usable product.
If you persist in struggling with the debian repositories, then you would be better off directing your complaints to the maintainers of those repositories.
I don't persist in struggling at all. I just trying to get this haphazardly tinkered product to work. I would rather struggle with my project, not with the tools.
