Noble install image does not have command-not-found database files

[Mike Ferreira]

Noble 24.04 Server edition daily dated 2023.11.03...

After install, type:
...
unknown-command

Error message:
Could not find command-not-found database. Run 'sudo apt update' to populate it.
unknown-command: command not found.
...

'apt update' does not populate it...

...
ls /var/lib/command-not-found
<no output = empty>
...

Should have files commands.db & commands.db.metadata, but doesn't. The folder is empty...

...
apt list command-not-found --installed
Listing... Done
command-not-found/noble,now 23.04.0 all [installed,automatic]
...

Reinstalling 'command-not-found' package does not create the files either...

So it seems that this package is broken, and not populating /var/lib/command-not-found with commands.db & commands.db.metadata files.

Since it was broken, and not working, that is why the system image that the installer extracted and copied over (via the curtin rsync) for the installation resulted in an empty folder for that.

This package needs to be repaired, before the image for Noble can by repaired, to fix it for the Noble Installer...

On my Ubuntu Noble problem seems disappeared:
corrado@corrado-n4-nn-0125:~$ pipponi
pipponi: command not found
corrado@corrado-n4-nn-0125:~$ entangle
Command 'entangle' not found, but can be installed with:
sudo apt install entangle
corrado@corrado-n4-nn-0125:~$ ls /var/lib/command-not-found
commands.db commands.db.metadata
corrado@corrado-n4-nn-0125:~$ inxi -Sxc

Does this commit also lead into or fix the newly reported Security "Command Not Found" db Vulnerability of introducing malware through the Ubuntu 'Command Not Found'? Or is that being handled separately?

Just asking...

[corrado venturini (corradoventu)]

this fix only concerns the absence of the database used by command-not-found
