Apt and Snaps of Same package but different versions...

Outabux · 12-26-2022, 02:11 PM

Installed plugin in Gnome Software for Snaps. Blender and FreeCAD weren't part of Bookworm at the time, so I added Blender and FreeCAD through Gnome-Software via Snap. Over Christmas day I got a present from Debian maintainers! It was Blender and FreeCAD! Yaay! Blender's an older version, but for me that's okay. FreeCAD is the same as the Snap, so the Snap version was removed with FreeCAD being installed via apt.

I'd love to create a system with only packages from Debian repositories kept in the sources.list or equivalent.

Anyway, I installed using apt Blender first and then Openshot-QT as separate apt install commands, as Openshot-QT depends on Blender. Removing Openshot-QT would have removed Blender; circular depends?

1) Anyway, is circular depends the correct phrase?

2) The only other Snap besides the latest Blender is Discord. I'd like to confirm that both Blender installations, the Snap and the one from Bookworm's repository will not interact. I believe that their configs and such are in different places in the home directory. Snaps' configs are inside ~/Snap/"application name". Once invoked, I believe that Blender from the repositories will be somewhere like ~/.blender.

I only need Blender because Openshot-QT needs it (animated titles), and I've been warned via website references to keep the versions the same. My sons will use Blender as well, and the new features are right up the alley of the eldest.

Appreciate your time & Happy New Year!

The Snap version of Blender does work. Openshot-qt installed from via apt which also depends on Blender works, at least loads fully. On the other hand, Blender via apt begins to initialize but never fully loads.

Barring that the two versions cannot coexist, is this a bug in Blender (via Bookworm apt repository)?

Thanks.

Openshot-qt still works. I just rendered a quick title which works fine. Wondering about the different versions of Blender and Openshot. Openshot is not available as a snap.

Is openshot-qt via apt using Blender via Snap as a dependency? ~/.config/blender/3.4 exists. So I guess openshot-qt is using blender and or its dependencies found in the snap installation. Man I hope I'm not mucking things up that may haunt me later.

If 3.4 comes into play from apt repository, how would snap removal affect the system?
What gets me is that openshot-qt would not install without the dependencies of blender found in apt. After doing the above, things just automagically worked. Hmmm.
