I think you’re likely right. I find these different methods of installing applications under Linux confusing.
I’m going to assume that the original install I been using for years isn’t snap. But how do you tell in advance? And how do you know how to upgrade using the right method?
When darktable gets a new release, what is the correct method of install? I’m fairly sure (but not absolutely sure) that originally (years ago) I installed from a 3rd party PPA. But I can’t actually remember how I installed all the various v3 and v4 versions. Was it from a PPA, was it direct from the website? No idea. I do a lot of messing around with Ubuntu following advice I find online but I have to say I don’t think conceptually I have a clue what I’m doing. When I get it to work, it’s a miracle!
So, at the minute I guess what I want to know is the steps required to get back to a stable working install under 23.10. Can I do that by downloading an install file from the darktable site? And can I retain all the previous settings and catalogue without losing anything? And do I have clear out stuff I’ve installed that isn’t working at the moment. And how do I do that?
A lot of questions, I know. Sorry
UPDATE: Apparently “$ snap search darktable” will tell me what darktable version is available as Snap. I get:
darktable 4.6.1 sergiusens - Virtual lighttable and darkroom for photographers
Which seems to confirm that 4.6.1 in the Ubuntu Software Centre is a Snap.
$ apt search darktable produces:
darktable/unknown 4.7.0~git870.a3140d3d-1+11523.1 ppc64el
darktable-tools-basecurve/unknown 4.7.0~git870.a3140d3d-1+11523.1 ppc64el
arktable-tools-noise/unknown 4.7.0~git870.a3140d3d-1+11523.1 ppc64el
Not sure why there are 3 separate things, but the first one suggests 4.70 is available as a whatever you call an app that isn’t a Snap. I guess this is what I need?
If I try “sudo apt install darktable”
I get:
Reading package lists… Done
Building dependency tree… Done
Reading state information… Done
darktable is already the newest version (4.7.0~git870.a3140d3d-1+11523.1).
0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.
Which I would guess means 4.7.0 is already installed.
If I run darktable from the launcher item, I get a spinning circle for a while, then nothing. if I run darktable from the command line, I get a core dump.
I found this error log darktable bt_xxxxx.txt file (there are lots of them xxxxx stands for the various numbers).
Is there a way to upload the file?
