I added a repository using
sudo add-apt-repository ppa:tualatrix/next
After adding it i get the message:
gpg: keyring `/tmp/tmpk2n9xi/secring.gpg' created gpg: keyring `/tmp/tmpk2n9xi/pubring.gpg' created gpg: requesting key 0624A220 from hkp server keyserver.ubuntu.com gpgkeys: key FE85409EEAB40ECCB65740816AF0E1940624A220 can't be retrieved gpg: no valid OpenPGP data found. gpg: Total number processed: 0
I even installed
y-ppa-manger and tried importing all the keys. Got success message there but that doesn't solve the GPG key issue.
Thanks in advance for any help and suggestions!
