I'm getting the following error when trying to update from repo:

W: GPG error: download.opensuse.org/repositories/home:/selmf/xUbuntu_18.04 Release: The following signatures were invalid: EXPKEYSIG 3F3411BE43F8BC1F home:selmf OBS Project <home:selmf@build.opensuse.org>
E: The repository 'download.opensuse.org/repositories/home:/selmf/xUbuntu_18.04 Release' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure( manpage for repository creation and user configuration details.

I've tried running:

wget -nv download.opensuse.org/repositories/home:...tu_18.04/Release.key -O Release.key
sudo apt-key add - < Release.key
sudo apt-get update

But no change. Any ideas?

Cheers,

I don't think I ever added a GPG key to the repo so that probably is the problem here. I also haven't updated the packages in a while, so I guess I should look into it.
Until then you probably could do an unsafe update.

Fair enough, I am guessing Mint update changed the default safe/unsafe settings at some point which is why the error started coming up.

Updating the repo at some point would be good.

Cheers,
