During upgrade from focal to jammy, mysql does not restart automatically, but holds up upgrade with an error dialog

3) I expect upgrade to 22 to happen as smoothly as possible
4) What happened dialogue (see below) appeared asking to restart mysql manually

When upgrading from focal (20.04.05) to jammy (22.04.01), upgrade stops midway through with the following dialogue:

┌───────────────────────────┤ Configuring libc6:amd64 ├────────────────────────────┐
│ │
│ Failure restarting some services for GNU libc upgrade │
│ │
│ The following services could not be restarted for the GNU libc library upgrade: │
│ │
│ mysql │
│ │
│ You will need to start these manually by running 'invoke-rc.d <service> start'. │
│ │
│ <Ok> │
│ │
└──────────────────────────────────────────────────────────────────────────────────┘

Logging in into another session and attempting to restart mysql while the dialogue is still up fails as well. However, it does succeeds seconds after clicking Ok.

The following shows up in journalctl -u mysql :
