upgradable but not upgrading from jammy-updates and jammy-security

I have upgraded from 20.04 to 22.04, and have two packages in state "upgradable" but not upgrading, which seem to have been kept back:

$ sudo apt upgradeReading package lists... DoneBuilding dependency tree... DoneReading state information... DoneCalculating upgrade...

What would you suggest for cleaning this up?
