This is really great to see. One issue with the released tarball though is no LICENSE or COPYING file indicating the license of its contents. Could that be fixed please?

Bug#1604: Mint 20.3 Update fails for latest release 4.1.0.4-0~1975~ubuntu20.04.1 - kdrive requirement xserver-x2go is missing
by Brian G 31 May '23

31 May '23

Package: x2goserver Version: 4.1.0.4 The update failed for mint 20.3 as x2goserver-x2gokdrive requires xserver-x2gokdrive which is not available in mint 20.3 and not available from the x2go repository. It screwed up my system pretty good! had to do a clean install of 4.1.0.3 to get up and running again. I have been using x2go for years, love it! And also some documentation file was moved in 4.1.0.3 to a different file in 4.1.0.4 and the upgrade complains about that before even reporting the kdrive issue on an attempt to do a fresh install of 4.1.0.4.

Bug#1434: Use login shell for session
by Orion Poplawski 30 May '23

30 May '23

Package: x2goserver Version: 4.1.0.3 Tags: patch X2Go's Xsession file always starts the user's session with /bin/bash (at least on RedHat systems where SHELL is set to /bin/bash via ~/.bashrc calling /etc/bashrc). This patch attempts to determine the user's login shell and use that for launching the session. See also: https://bugzilla.redhat.com/show_bug.cgi?id=1794660 Another option might be the judicious use of the --norc option when launching x2goruncommand on followers but I'm not sure what other effects this will have or where to do that. Effects might not be to bad because I can simulate this by moving away the user's .bash_profile and .bashrc files and then the tcsh is used as expected in this case. However, while $SHELL does not get set in this case, the xfce4-session script still gets launched with bash which triggers some other errors, so this patch may be the best option. --- x2goserver-xsession/etc/Xsession | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/x2goserver-xsession/etc/Xsession b/x2goserver-xsession/etc/Xsession index 270a0b3..522f37e 100755 --- a/x2goserver-xsession/etc/Xsession +++ b/x2goserver-xsession/etc/Xsession @@ -117,6 +117,10 @@ if ! echo "*" >>"$WRITE_TEST"; then fi rm -f "$WRITE_TEST" +# Determine the users login shell and use that to launch the session +SHELL=$(getent passwd $LOGNAME | cut -d: -f7) +# Fallback +[ -z "$SHELL" ] && SHELL=/bin/bash if [ -f /etc/debian_version ] || [ -f /etc/devuan_version ]; then -- 1.8.3.1 -- Orion Poplawski Manager of NWRA Technical Systems 720-772-5637 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 https://www.nwra.com/

Package: Pyhoca Version: 0.6.0.1 I tested all combinations of the following recent releases of the following software from the ppa:x2go/stable and ubuntu repositories: + x2goserver + 4.1.0.0-3 (ubuntu) + 4.1.0.3-0~1708~ubuntu18.04.1 (ppa:x2go/stable) + x2goclient + 4.1.1.1-2 (ubuntu) + 4.1.2.1-0~1788~ubuntu18.04.1 (ppa:x2go/stable) + pyhoca-cli + 0.5.0.4-1 (ubuntu) + 0.6.0.1 (ppa:x2go/stable) There is one combination that did not work: x2goserver 4.1.0.3-0~1708~ubuntu18.04.1 (ppa:x2go/stable) with pyhoca-cli 0.6.0.1 (ppa:x2go/stable) It failed with the following message, which I assume is a bug: " a bytes-like object is required, not 'str' pyhoca-cli: error: the remote server does not have the X2Go Server software installed "
