GPG error on update

[bshor]

Hello, I'm running a variant of Fedora 40 (Nobara). cran2copr has worked amazingly for me so far.

But today, I am getting a GPG error in the system updater while trying to update cran-tm.

Error: GPG check FAILED

This is a problem for updating R packages, but it's also stopping me from updating my system as a whole!

In any case, would be happy to troubleshoot, let me know what info you need. Thanks!

Apparently this is an open issue, see fedora-copr/copr#2894

For now, the workaround is to manually drop the old key and import the new one. In our case:

$ # drop the old key
$ sudo rpm -e gpg-pubkey-1a3b4456-5d54ab50
$ # install the prolonged one
$ sudo rpm --import https://download.copr.fedorainfracloud.org/results/iucar/cran/pubkey.gpg

Let's keep this issue open for visibility, because other users will hit the same wall.

This worked! Agreed on keeping it open.
