Release Key for OpenARC Builds has expired

[MrPeteH]

It's a bit tough to install without a current key ;)
https://download.opensuse.org/repositories/home:/andreasschulze/Debian_10/Release.key

Workaround:
deb [allow-insecure=yes] https://download.opensuse.org/repositories/home%3A/andreasschulze/Debian_10 ./

OpenARC releases in this repository are not signed.

Better report this wherever you found the signed artefact. There is nothing that can be done here.

I will try to find him... unfortunately, the openarc email listserver also appears busted: it doesn't confirm a subscribe...

[andreasschulze]

the key was automatically updated today. Could you contact me directly with information about your your issues with the listserver?

Ugh. @andreasschulze infrastructure changes in the Debian/Ubuntu apt-* world have obsoleted quite a few signing methodologies. I've gotten as far as finding a set of commands that can convert an auto-created Release.key file into a valid signature in a "modern" no-more apt-key context. This can probably be simplified... and I suspect there's an appropriate new keyring file that opensuse (??) ought to be providing (see https://wiki.debian.org/DebianRepository/UseThirdParty#OpenPGP_certificate_distribution)

(My source of insight for the following is the top answer in https://askubuntu.com/questions/1286545/what-commands-exactly-should-replace-the-deprecated-apt-key )

#all under sudo
wget https://download.opensuse.org/repositories/home:/andreasschulze/Debian_11/Release.key
gpg --no-default-keyring --keyring ./temp-keyring.gpg --import Release.key
gpg --no-default-keyring --keyring ./temp-keyring.gpg --export --output home_andreasschulze.gpg
rm temp-keyring.gpg*
mkdir /etc/apt/keyrings
chmod 755 /etc/apt/keyrings
mv home_andreasschulze.gpg /etc/apt/keyrings/

Now insert the following or equivalent into sources.list.d/openarc.list
deb [signed-by=/etc/apt/keyrings/home_andreasschulze.gpg] http://download.opensuse.org/repositories/home:/andreasschulze/Debian_11/ /
Voila, updates are again working.
