Backintime fails to open after installing PyQt5

[adamfries92]

Mostly free install of Ubuntu Gnome 16.04 (just ran a script that downloads a few programs and setups up a few directories/symlinks). Once everything was setup the way I wanted and backintime working fine, wanted to get PyQt5 up and running for dev work.

Installed PyQt5 from the command line (believe I used sudo apt-get install python3-pyqt5*). Now, backintime wont open, and gets a sementation fault if I try to run it from the command line.

I have another computer (Running Ubuntu 16.04) that I went through the same process of installing PyQt5. Backintime works fine on that computer.

Any help would be appreciated!

Which BiT version did you install? Current stable 1.1.20 from official repository still uses Qt4. Only 1.2.0~alpha from ppa:bit-team/testing uses python3-pyqt5. Please run backintime-qt4 --debug from Terminal and post the output (or if you're using BiT 1.2.0 the command is backintime-qt --debug)

I am running Linux Mint 18.1 and I recall having something similar, but don't remember how I fixed it now. I believe I had to also install the package "python3-dbus.mainloop.pyqt5". This is with 1.2.0~alpha.

[adamfries92]

Sorry for the delayed response.

I am running version 1.1.12 from the 16.04 official repo.

Running the debug I get a segmentation fault.

[Germar]

Maybe related to #713? Please remove both python3-pykde4 and python3-pyqt4

[Germar]

Oh, just saw you are still on 1.1.12. So please remove python3-pyqt5 or upgrade to BiT 1.2.0 from testing PPA

[adamfries92]

I updated to BiT 1.2.0 from the PPA. Running it from the command line, I get below:

adam@ubuntu-desktop:~$ backintime --version 
backintime 1.2.0~alpha16
adam@ubuntu-desktop:~$ sudo -i backintime

What is the output of systemctl status dbus.service?

I have same issue and after trysudo -H pip3 uninstall sip I get Cannot uninstall requirement sip, not installed.

I think it's not related with sip.

I haven't been able to run backintime for some weeks. If I run backintime-qt4 (with or without --debug) I get "segmentation fault" I have removed all pyrthon3-ptqt5 packages but still get the same result. I'm afraid I am not well up on the technicalities so I do not have much idea on further action. Is there any further information I can provide ?

I reported the problem on the Mint xfce forum https://forums.linuxmint.com/viewtopic.php?f=57&t=253316&p=1363579&hilit=backintime#p1363579 and didn't get very far.

I've got about a Gb of backups (which I can just about access) but haven't done a Bit backup for some months

Guys, I have a similar issue, after installing PyQt5 all went up in smoke, BackinTime (BIT) stop working all together and refuses to start throwing the following error: backintime traceback Traceback (most recent call last): File "/usr/share/backintime/common/backintime.py", line 27, in import config File "/usr/share/backintime/common/config.py", line 32, in import tools File "/usr/share/backintime/common/tools.py", line 51, in import dbus ModuleNotFoundError: No module named 'dbus'

I've tried to install all the libraries suggested to no avail. I am at lost as to what to do. This doesn't seem to be a particular issue, I've seen it in a few places with no solutions or not a clear specific solution for BIT. I'm appealing to anybody clue enough to tell us, step by step how to check (please provide commands if possible) and then what are the corrective steps (again include commands).

Regards

[malypetu]

Just to add a bit of information, I've run as suggested by Germar:

sudo python3 /usr/share/backintime/qt/serviceHelper.py sudo python3 /usr/share/backintime/qt/serviceHelper.py Segmentation fault (core dumped)

Hope this helps a bit to isolate the issue.

Cheers

[buhtz]

Because the Issue is quit old: Can anyone reproduce the problem with the current version of bit and operating system?

[aryoda]

May be related to #871.

Try to install the mentioned packages (where pyqt5 is already installed causing the problem ;-)

pip install dbus-python and pip install pyqt5
