So, Davinci Resolve’s .run file used for installation definitely somehow interacted with the package manager. Otherwise, the system wouldn’t break the way it did. While, technically the package manager was in use (at least at some point), the user -i.e. OP- did not intentionally invoke its use consciously. So, I wouldn’t refer to this as “using the package manager”.
They just installed a apt.source
What is an apt.source? Search engines and LLMs failed at resolving this. They did explain what apt source is or could refer to, though*. Regardless, what leads you to understand that they’ve installed an apt.source? Please be elaborate as I’m not a Debian/Ubuntu user; consider shedding light on it through the RPM world.
THAT I would say one should not do unless one really knows what they are doing.
How does one know which apt.source they should and should not install? Doesn’t this imply “expert skills” (using my understanding of your logic)? On Windows, you can install software with almost no fear; as long as the source is trusted.
If they had just installed some .appimage
Assuming they’ve installed libfuse2. Which actually is not present in modern Ubuntu installations.
or compiled something from source they would have been fine.
So, in this case, you believe that compiling a gargantuan program like Davinci Resolve would not have caused a ton of issues related to dependencies even if it was supported on Ubuntu?
So… I’m not going to nuance your stance if it shouldn’t be nuanced.
I thought that my writing was sufficiently easy to comprehend and would not lead to any misunderstandings. Therefore, within that context, nuance was not needed. However, your engagement in the conversation implies that some actually did misunderstand it. Thus, nuance was (seemingly) needed and I only became aware of it afterwards.
It’s a bit up to you to be clear about your nuance. And in this case you’re being very ambiguous about it.
My stance is pretty simple:
Use whatever is provided, intended and supported by the ‘distro’.
For that which goes beyond this, you’re on your own and should be prepared to face the consequences.
So, if one can’t deal with the consequences, like how OP had to come here for help, then one should stick to the first point.
