Submitted by Patrick Schleizer

Link to original bug (#15282)

Description

Expected Behavior
  • Same behavior as with sudo --set-home.
  • Editor opening.
Current Behavior
lxsu exo-open test.txt ; echo $?

0

Editor does not open.

Steps to Reproduce (for bugs)
  1. upgrade Debian stretch to Debian buster (in Qubes OS pr real Debian buster)
  2. sudo apt-get install --no-install-recommends lxqt-sudo
  3. touch test.txt
  4. lxsu exo-open test.txt
Context

desktop shortcut using lxsu (to get root rights, to have a password prompt), followed by xdg-open (which is supposed to select the user's favorite chosen text editor rather than hardcoding any specific one [or inventing a custom mechanism for choosing one]).

exo-open comparison with non-root and sudo behavior
  • touch test.txt
  • works: exo-open test.txt
  • works: sudo --set-home exo-open test.txt
  • fails: lxsu exo-open test.txt
  • fails in Qubes Debian buster as well as real Debian buster
env comparison with non-root and sudo behavior

Perhaps environment has something to do with it? I guess not. Just in case attaching the different output.
