[xubuntu-users] Synaptic problems?

[Ralf Mardorf]

First of all

I wonder how you enable to get Re: Re: Re:.

Another hint
============

If you're using another language, but English, launch commands by

  LANG=C <command>

to temporarily get English output.

Regarding the topic
===================

The permission for the directory partial/ should be _apt:root. However,
you safely could remove the directory and it's content

  sudo rm -r /var/cache/apt/archives/partial/

or be overcautious and move it away, so you could restore it

  sudo mv -i /var/cache/apt/archives/partial/ /root/partial.bak

Then run

  sudo apt update
  sudo apt install -f
  sudo apt full-upgrade
