Thank you for your reply. I tried installing it again and got the same problem and the output looks identical. Nonetheless, here is the new output: https://paste.yunohost.org/raw/puyuzigale
grep -nr 'debian.org' /etc/apt/sources.list*
Doesn’t output anything. The file /etc/apt/sources.list only contains
deb http://raspbian.raspberrypi.org/raspbian/ buster main contrib non-free rpi
The file /etc/apt/sources.list.d/photonix.list contains
deb https://dl.yarnpkg.com/debian/ stable main
Does that help? I have other *.list files corresponding to other apps.
– Edit to add - -
The webadmin throws out an error when I try to update. And when I run sudo apt-get update on the command line I see that it’s the same public key error. So I update the distro, and then use checkrestart and clean up some old files. (I followed yunohost’s troubleshoot guide up until that point).
The public key error still persists, so I read up on keys and keyservers, and I try to add the keys in the error with
gpg --keyserver keyring.debian.org --recv-keys <PUBLIC_KEY>
Which gives me the following for both keys (except the first line, it only appeared when I ran the command for the first time)
gpg: keybox '/home/admin/.gnupg/pubring.kbx' created
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0
And the error still persists. So based on this, it looks like the server can’t get the public keys for http://cdn-fastly.deb.debian.org/debian, or at least not from keyring.debian.org
Am I understanding the problem correctly or am I off on a wild goose chase?
– Edit again—
I tried getting the keys without specifying server:
$ gpg --recv-keys 648ACFD622F3D138
gpg: key DC30D7C23CBBABEE: new key but contains no user ID - skipped
gpg: Total number processed: 1
gpg: w/o user IDs: 1
It still throws out the public key’s error.
Thanks for your help
