[SOLVED] Identifying Ubuntu Sources

[jglen490]

Is there a reason why /etc/apt/sources.list.d/ubuntu.sources information does not show up in Synaptic?

[Snowhog]

Not !00% sure, but I don't think Synaptic sees anything (by default) under sources.list.d, which is where "custom" URIs now go. Synaptic is 'old', so...

You can add your custom URIs to Synaptic.

O.K., the chrome deb resource shows, but not the core stuff.

And, yes,

apt-add-repository --list

will list it all, but I kind of got hooked/spoiled on Synaptic showing the resources. Oh well

I thought that to be used the files in /etc/apt/sources.list.d have to have the .list file name extension, and that anything else is ignored.

[jglen490]

That's what used to happen! The list that shows in

apt-add-repository --list

is formatted a bit differently, now. What I did "discover" , is that Discover Settings now shows the repo output in the format that Synaptic used to show it. However, the Ubuntu repo is indicated by the first few line ins the list file.

See Ubuntu’s Repository Configuration: Ubuntu sources have moved to /etc/apt/sources.list.d/ubuntu.sources for further details.

I just can guess that Synaptic cannot handle .sources files (I rarely use Synaptic)…

Is synaptic opening the separate Software Sources utility, the same one opened in Discover (and Muon), or is it opening something that looks different?
Synaptic will, or used to, open the *buntu Software Sources tool (software-properties-qt or -gtk) if It has its own crappy and simpler tool for managing repos, if the Ubuntu one isn't there.
So any oddities would be from the Software Sources tool, most likely.

Synaptic opens a completely different looking app when selecting the Repositories menu option.

I think my memory is jumbled. Synaptic probably wants the Ubuntu/gtk version software-properties-gtk.
yup, it needs it:

Before and after:


yes, this is a Jammy VM running on my NAS/Homelab PC, as I don't have a 24.04 system handy.

Apparently, what I've installed for Kubuntu all these years, has "just worked". So I'll look at

software-properties-gtk

when i get a moment and see if it "just works" again

[jglen490]

claydoh that was it. The repo display for Synaptic now looks like it used to, and Discover shows the same portrayal. Of course Calamares did set up the repos to follow the new listing method, as shown by

apt-add-repository --list

. It's just different, but it works and did get a new update notification this evening. apt update and apt full-upgrade work just as always.

Discover used to have a useful screen that showed a bunch of Ubuntu repositories that were available/subscribed to and that has now disappeared.

[jglen490]

And that's because the repo "list" has changed format and location. Should there have been better cross-talk with Discover when this happened? Of course, but apparently it didn't. So give up? Hell no. Discover may catch up at some point. Until then use the solution in posts #2 and #3, above. And apt knows where they are.

Lots of tools have problems. I did a release upgrade on a VPS, and something found a .list left over from the original install in 2019 and converted it to a .sources, which lacked a "signed-by" (or something similar). I could just delete it, but I had to work that out.

APT was so solid for such a long time... IMO it's not surprising that eventually it needed changes that are causing trouble.
