Unable to generate metadata on Ubuntu 23.04

[jhonny-oliveira]

Hi!

I'm getting the error (crash) below, while attempting to generate the metadata for my repo on Ubuntu 23.04 (Generator version: 0.9.0).

Any idea about what might be happening?

std.file.FileException@std/file.d(4717): /home/xd/.aptly/public/ubuntu/cache/tmp/asgen-Xdhknp38/ubuntu/langpacks/var/lib/locales/supported.d: No such file or directory

You can find additional information and the full execution log here: appstream-generator_log.txt.

Thank you!

@jhonny-oliveira:

Hello,

Do you try to generate the metadata with your local repository under Ubuntu 23.04 ? I'm trying to use my local repository with Gnome Software but it seems that I must use appstream-generator to have 'appstream catalog metadata' which Gnome Software requires. If you trying to do the same thing, can you give me advice for it ? I'm also on Ubuntu 23.04 version.

Thank you very much.

@jhonny-oliveira: Does your repository even contain language packs? If not, does the issue go away if you simply use the "debian" backend instead of the Ubuntu one?

@Tuxman2 ,

You can find below a raw dump of what I have done. I created a mirror of my PPAs with aptly excluding the packages that cause the crash and then run the appstream-generator. When/if I ever get this working I will create and publish a nice HowTo with it. Let me know if you can make anything out of it and/or if I missed something.

# Create appstream directory
mkdir ~/.aptly/public/appstream/ubuntu

# create metadata

sudo apt update

@jhonny-oliveira: Thanks for your help.

I've got a local repository made with the help of apt-mirror. I've got DEP-11 metadata but I can't install any software under Gnome-software with the help of my local repository. As I said on another topic, I can see the list of applications, do a research on a software, but when I push the install button, it's waiting but nothings happens. It seems that Gnome-software tries to contact stackedit.io and appstream.ubuntu.com websites but I'm not online. I try to find a way to install sotfware under Gnome-software offline with the help of my repository (available on external hard disk).

Thanks.

Regards.

Note: I'm using Ubuntu 23.04.

@Tuxman2 ,

If I understood correctly, you have it working (almost) but the install fails. Correct?

I didn't get that far. Can you please provide me more details, so I can understand what I'm missing.

I don't need to be offline. So, that's not a issue for me.

[Tuxman2]

@jhonny-oliveira: Yes the install fails, but it is very strange that I can see the list of applications and do research on a software. I define my local repository in /etc/apt/sources.list file. Like this: deb [arch=amd64 trusted=yes] file:/media/......./....../ubuntu/ lunar main restricted universe multiverse

In the terminal, I can install software with the sudo apt install command. I can do updates too. I tried with Ubuntu Software but it crashes with it. So, I installed Gnome-Software. When I push on the install button, another button appears: "Cancel" and after that an item is displayed below: "Ubuntu Unknow source Deb". I'm waiting but nothing happens. My local source repository is well defined in Gnome-Software.

Can it be a Gnome-Software bug ? When I'm online everything is ok.

[jhonny-oliveira]

Dear @Tuxman2, I just found out that aptly doesn't support dep11 (aptly-dev/aptly#473).

Can it be a Gnome-Software bug ? When I'm online everything is ok.
I don't know and I have no chance to test it at the moment.

Can you please share the recipe you followed using apt-mirror?

@ximion ,

I confirm 8750a92 fixed the problem.

Thank you!

Hello,

I dropped this problem. I don't have time to deal with it anymore because of my job. I returned to Manjaro and its pamac tool.

Thanks for taking the time to help me.

Regards.
