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-pyqt5 5.13.2-8 update today.

usulofarakis · 2019-12-16T19:10:12Z

The issue was resolved with the python-pyqt5 5.13.2-8 update today.

Confirmed, now running as expected.

picousse · 2020-05-13T09:40:41Z

I still got the same error with version 5.14.1 (ubuntu 20.04)

picousse · 2020-05-13T10:02:05Z

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

bighegi · 2022-01-17T18:19:41Z

Same Problem here,
Ubuntu 20.04 LTS, python3-pyqt5-5.14.1+dfsg-3build1, same error:

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"?

emtiu · 2022-09-23T11:35:52Z

Thanks for the good spot! I'll try and combine/collect those Issues. Yes, 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.

buhtz · 2022-09-26T08:43:56Z

If this here is the main/collecting issue for all the duplicates can we modify its title to a more informative one please?

emtiu · 2022-10-08T21:58:41Z

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 :)
