Hey, I've tried to Upgrade my Zorin OS Pro Lite installation through the provided tool. It quickly failed, when I ran apt-get update on the commandline I was met with this message.
Err:15 https://packages.mozilla.org/apt mozilla InRelease
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY
I fixed it by running the following commands and verified, that the command does now work correctly
sebastian@sebastian-linux:~/Documents/Coding/nethogs$ gpg --keyserver keyserver.ubuntu.com --recv-keys C0BA5CE6DC6315A3
gpg: key C0BA5CE6DC6315A3: public key "Artifact Registry Repository Signer <artifact-registry-repository-signer@google.com>" imported
gpg: Total number processed: 1
gpg: imported: 1
sebastian@sebastian-linux:~/Documents/Coding/nethogs$ gpg --export --armor C0BA5CE6DC6315A3 | sudo apt-key add - && sudo apt-get update
OK
After that I ran the upgrade utility again, it got further into the upgrade process and then failed again. Now I feel like I am stuck.
