Ubuntu – Authentication failed upgrading from 19.04 to 19.10

19.10authenticationupgrade

It's Kubuntu to be more precise. BTW my network works and i have tried to remove the 32bit architecture/packages.

sudo do-release-upgrade
Checking for a new Ubuntu release
Get:1 Upgrade tool signature [1,554 B]

authenticate 'eoan.tar.gz' against 'eoan.tar.gz.gpg' 
Authentication failed
Authenticating the upgrade failed. There may be a problem with the network or with the server.

EDIT: So what i did was to open sources.list and substitute "disco" with "eoan". It everything works so far after the upgrade.

  • bentolor's answer led me to a different command which seemed to ultimately fix the problem:

    sudo apt-get install --reinstall ubuntu-keyring
    

    I'm guessing this restores the keyring to defaults, something must have changed since the package was last installed. Now I can run the command sudo do-release-upgrade -m desktop without the Authentication failed error.
