Hello I'm trying to upgrade ubuntu Ubuntu 16.04.5 LTS to latest
# do-release-upgrade
Checking for a new Ubuntu release
Get:1 Upgrade tool signature [819 B]
Get:2 Upgrade tool [1,258 kB]
Fetched 1,259 kB in 0s (0 B/s)
authenticate 'bionic.tar.gz' against 'bionic.tar.gz.gpg'
gpg exited 2
Debug information:
gpg: Signature made Wed 29 Aug 2018 09:33:13 PM EEST using RSA key ID C0B21F32
gpg: Can't check signature: public key not found
Authentication failed
Authenticating the upgrade failed. There may be a problem with the network or with the server.
I keep getting this, i tried to search for the key by the C0B21F32, but didn't find anything, what should i do next?
