I am getting a few errors when doing apt-get update. Some seem fatal, some are just ignored, but anyway I want to remove them to prevent further issues.

It was working until I added:

add-apt-repository ppa:scribus/ppa

The first error is:

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

This does not seem to cause issues, as saw it before. But, it still appears each time.

The second error is:

W: chmod 0700 of directory /var/lib/apt/lists/partial failed - SetupAPTPartialDirectory (1: Operation not permitted)

One last error is:

E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied)

There are other errors, but I will list them once I correct these.

  • You should use pastebin.com, and post all of the output as is, without any kind of editing. Anyway, the first one is obvious, it should be 50unattended-upgrades without that stuff at the end. Feb 11, 2017 at 12:45
  • 'permission denied' usually means you ran the command without sudo.

  • OK, the sudo addition helped. Thanks. Iforgot.. I did add the full new text from the sudo apt-get update: pastebin.com/w9se5LG3 I still seem to get the first error that I got last time.

Just remove it is unnecessary:

sudo rm /etc/apt/apt.conf.d/50unattended-upgrades.ucf-dist
