[Bug 1925840] [NEW] update-notifier says "(null)" on first boot after a release upgrade

[Marius Gedminas]

Public bug reported:

Upgraded my Ubuntu 20.10 to 21.04 with sudo do-release-upgrade -d,
rebooted, and got this window in my face a couple of minutes after
booting (see attached image).

It is shown by update-notifier and says (null), then gives me an option
to [Perform this action].

lsof -p $(pidof update-notifier) shows

    ...
    update-no 4269   mg   16r      REG              259,5     1025 14027136 /usr/share/ecryptfs-utils/ecryptfs-record-passphrase

so it is probably trying to tell me to record my ecryptfs recovery
passphrase?

(For the record, my ~/Private is correctly unlocked and mounted.)
