[Bug 1946196] Re: Additional Drivers fails with pk-client-error-quark: Cannot download packages whilst offline (257)

[Andrew Enderson]

While trouble shooting something else, I used the Driver Manager in
kubuntu System Settings (which uses Additional Drivers) to uninstall the
nvidia driver (nvidia-driver-390). After finishing the trouble shooting,
I attempted to reinstall the nvidia driver via Additional Drivers, and
I'm getting this error as well.

After seeing message #1, I also attempted to launched the Discover
package manager, and Discover is reporting the error as well: Cannot
refresh cache whilst offline.

I've recently run sudo apt update && sudo apt full-upgrade, so the
system appears to be up to date.

Distributor ID: Ubuntu
Description:    Ubuntu Impish Indri (development branch)
Release:        21.10
Codename:       impish
