Anyone an idea what to do?
Same here on Manjaro Linux and building from source fails during the test. It seems to be something with python-dbus. I have v1.2.14 installed.

The issue was resolved with the
python-pyqt55.13.2-8 update today.
Confirmed, now running as expected.
I found a solution, However not sure what did the trick...
I uninstalled pip3 PyQt5 and installed using python3-pyqt5
Fixed it for me on ubuntu 20.04
running /usr/bin/python3 -Es /usr/share/backintime/qt/serviceHelper.py was helpfull
Same Problem here, Ubuntu 20.04 LTS, python3-pyqt5-5.14.1+dfsg-3build1, same error:
$ backintime-qt

Interesting though, I have another similar machine just with slight differences and there BIT works normal. The challenge is to find the difference ... but I got no good idea where to start. All installed BIT and python3-pyqt5* packages are the same ...
Thanks a lot in advance! Stefan.
Thanks for reporting and debugging! Does this bug still happen for anyone, or have updates eliminated the problem?
dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NameHasNoOwner: Could not get owner of name 'net.launchpad.backintime.serviceHelper': no such name
This error message is reported in several issues:
Related to: #1233, #1014, #1013, #963, #921, #756 Possibly also to: #1068
@emtiu Could/should this type of issue be "escalated" to a "high incident"?
Thanks for the good spot! I'll try and combine/collect those Issues. Yes, https://github.com/bit-team/backintime/labels/High is the right label for this problem.
It's always the rolling release distros that run into this kind of trouble, isn't it? ;) Moving target makes it so much harder to reproduce.
If this here is the main/collecting issue for all the duplicates can we modify its title to a more informative one please?
Closing as duplicate of #921.
@bighegi: Your report is almost the only one about this problem from a recent, non-rolling-release distro. Please comment in #921 if you have more information. Thanks :)
