message regarding ignoring 50unattended-upgrades.ucf-dist is annoying

[richud]

Regression problem, (in the sense it didn't happen before the update although not directly from the code changes)

Since update to 0.90ubuntu0.1 (ubuntu 16.04) I am constantly now getting this notification performing anything with apt.

N: Ignoring file '50unattended-upgrades.ucf-dist' in directory '/etc/apt/apt.conf.d/' as it has an invalid filename extension

Secondly I am also now getting this, triggering apport bug report on every boot (program is not checking/creating a dir before trying to write to log in it)

The FileNotFoundError is covered by bug 1590321 and I'm working on fixing it now.

great, also bug #1236059

Patch has been committed to upstream git that fixes the problem with "N: Ignoring file '50unattended-upgrades.ucf-dist' in directory '/etc/apt/apt.conf.d/' as it has an invalid filename extension"

Right, I hope I don't forget to close the bug when uploading 1.4.

[Josh Littlefield (jblittlefield)]

The patch works around the issue in apt, but isn't the underlying cause the fact that /etc/apt/apt.conf.d/50unattended-upgrades was a confffile in ~0.82.1ubuntu2.3, and is no longer a conffile in ~0.90ubuntu0.3, yet the typical pattern for obsoleting a conffile wasn't performed? So even an unchanged 50unattended-upgrades is seen as a conflict by the ucf code, and thuse the .ufc-dist file is created, and the user is asked to resolve a "conflict" in a file that wasn't changed.

[Julian Andres Klode (juliank)]

I don't know, but it certainly is right to ignore the file in apt.

[Balint Reczey (rbalint)]

Unattended-upgrade uses ufc(1) to manage the related conffiles and ucf creates those copies during the update.

Starting with u-u 1.4 README.md recommends creating separate configuration files in /etc/apt/apt.conf.d to avoid updates to conflict with local changes.

Latest apt ignores the .ucf-* files which is the right thing IMO and either giving warning or not giving a warning is OK on apt's side.
