Comment 60 for bug 1690980

@Ethan Yes, the "All upgrades installed" message is still misleading.

Note however that there are two modes of u-u you can operate in on shutdown and they are picked by setting Unattended-Upgrade::InstallOnShutdown.

When it is set to True u-u runs to completion (unless it times out after 15 minutes).

In the other case (set to false) shutdown gracefully terminates u-u with the current fixes possibly (and probably) not installing every update. In that case the message is clearly misleading.

I'm updating the message, but I believe that this is how u-u is expected to operate.
