I don't remember when I first downloaded the key, probably a couple of years ago, I updated it a few days ago since APT then started displaying errors about it having expired.

Err:7 http://download.opensuse.org/repositories/home:/manuelschneid3r/xUbuntu_22.04 InRelease
The following signatures were invalid: EXPKEYSIG 1488EB46E192A257 home:manuelschneid3r OBS Project home:manuelschneid3r@build.opensuse.org

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://download.opensuse.org/repositories/home:/manuelschneid3r/xUbuntu_22.04 InRelease: The following signatures were invalid: EXPKEYSIG 1488EB46E192A257 home:manuelschneid3r OBS Project home:manuelschneid3r@build.opensuse.org

W: Some index files failed to download. They have been ignored, or old ones used instead.

So I tried it again today, downloaded the key from http://download.opensuse.org/repositories/home:/manuelschneid3r/xUbuntu_22.04

I did a simple test by downloading all the keys from https://software.opensuse.org/download.html?project=home:manuelschneid3r&package=albert and then doing a gpg --show-keys home_manuelschneid3r.gpg on them, and the ONLY key that doesn't seem to be expired, is xUbuntu_24.04/Release.key

APT error: (the key I'm using is xUbuntu_22.04/Release.key)

I talked to the guys at OBS. OBS does not implicitly update keys in any way for deb systems. seems like yum handles key updates implicitly. Thats horrible because probably every user will unfortunately notice it. Looking for a solution now. Probably a keyring package can help. This is absolutely frustrating. I just spent months trying to go with flatpak because distribution on linux is such a pain. However it is pretty invasive (the project itself has to be flatpak aware which is a huge amount of work).

[ManuelSchneid3r]

The distro specific keys are updated only on a publish and only if expired.

To fix the key issue for now importing an updated version should help:

curl -fsSL https://build.opensuse.org/projects/home:manuelschneid3r/signing_keys/download?kind=gpg | gpg --dearmor > /etc/apt/trusted.gpg.d/home_manuelschneid3r.gpg

Please let me know if this works for you.

Your fix with the new signing keys worked great on my Linux Mint 21.3 (Ubuntu 22.04-based), now APT works and no more errors! Thanks for the quick fix!

[ManuelSchneid3r]

Great! the guys at OBS made expiration user configurable. openSUSE/open-build-service#16082. I guess setting the expirations to like 6 years should suffice for like 99% of the users.
