I have currently running Ubuntu 21.04 and trying to upgrade to 22.04
once I do
sudo apt update
sudo apt upgrade
sudo do-release-upgrade
I get the following authentication error
Blockquote s" async=""> Continue [yN] y Get:1 Upgrade tool signature [691 kB]
Get:2 Upgrade tool [691 kB]
Fetched 691 kB in 0s (0 B/s)
authenticate 'jammy.tar.gz' against 'jammy.tar.gz.gpg' Authentication failed Authenticating the upgrade failed. There may be a problem with the network or with the server.
What are my options here to rectify this. I have good network connection and don't understand the server issue.
