[kubuntu] "Release notes" link doesn't open

[Jean-Baptiste Lallement]

On Kubuntu (20200731), the release notes link doesn't open on click.

xdg-open uses the following call: kde-open${KDE_SESSION_VERSION} "$1"
but KDE_SESSION_VERSION is not set when xgd-open is executed and it executes kde-open (which doesn't exist) instead of kde-open5.

This sounds like the root cause of my bug: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1681144

[Jean-Baptiste Lallement (jibel)]

@Marco, it's likely the same root cause.

You can check if in /var/log/installer/debug there is an error similar to :
/usr/bin/xdg-open: 604: kde-open: not found

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Chris Guiver (guiverc)]

Just an FYI: My last test with Kubuntu 20.04.1 was with 31-July-2020 ISO and the link didn't work, and was noted in comments on iso.qa.ubuntu.com. I made comment on IRC too asking if bug was wanted but didn't get reply.

[Jean-Baptiste Lallement (jibel)]

Actually the KDE_SESSION_VERSION is set to 4 instead of 5 in kde_ui.py. I'll submit a fix.

  [ Jean-Baptiste Lallement ]
  * AD integration for GTK UI.
  * bump KDE_SESSION_VERSION to 5 to fix xdg-open on Kubuntu (LP: #1890173)

  [ Brian Murray ]
  * Do not try to keep installed software when reinstalling Ubuntu as the
    process was error prone (LP: 1152399) and did not provide a quailty
    experience. (LP: #1798369)
