After finishing and quitting python3 activity still running

[wolftune]

On Ubuntu based system w/ BIT 1.3.1

I can run backups, get to done, quit the GUI, and then two backintime-related entries persist in System Activity: encfs (user owned) and a Python process (root owned).

[wolftune]

Update, I ran backintime-qt in command line, same error. When I choose "quite" in the GUI, nothing showed in the command line. When I did ctrl-C, I got a traceback

KeyboardInterrupt:

And even then, a python3 activity remained listed under root within System Activity, and I had to sudo kill -9 to stop it

Hi @wolftune, if you're still running backintime and still encountering this problem: Could you post the console output again, this time running backintime-qt --debug?

This might have something to do with something weird with my mountpoint setup, dunno. Okay, yeah, I see the ghost thing in Dolphin still, something weird there. I'll get that cleared and then revisit this after logging out and in.

I do recall something before where the problem was that a status of something would make BiT crash, and when I added some ignore (which I didn't want backed up anyway, something that was like BiT's own config or temp area) the crashing ended. Then, it was less of a problem for BiT process to linger because having it linger didn't block me from opening it again (unlike the current status).

[wolftune]

Okay, I tried after restarting and with a drive that successfully and fully unmounted afterwards.

I still have backintime running after quitting the GUI. Two processes showed "backintime-qt" and "python3" from /usr/bin/python3 -Es /usr/share/backintime/qt/serviceHelper.py (double instances, one user one root)

If I force the user instance of python3 process to close, backintime-qt stops too. Not so the other way around.

No errors in the debugging (the only error is in the drive missing)

I noticed that when I closed the GUI debug version, nothing showed in the CLI at all. It's as though the GUI closing is just doing nothing. The processes only stopped at all after I did ctrl-C in the terminal.

Thanks a lot for the debug info! We'll see if we can get this reproduced.

One of the permanently running BiT processes works as designed:

> ps aux | grep -i backintime
root        2473  0.0  0.0  70552 22032 ?        S    Nov08   0:00 /usr/bin/python3 -Es /usr/share/backintime/qt/serviceHelper.py

BiT installs a D-Bus listener to change udev rules and this is contained in the serviceHelper.py (a root daemon).

Why the GUI doesn't quit or is still running in the background I cannot figure out but when I start the GUI (non-root) and just quit it without doing anything else I can see more debug output (with the newest version at master branch) so something seems to block in your case.

Here is the missing debug output when quitting (as said: I use Git HEAD of master so the output may look different to yours):

Are you

• using a user-callback script?
• storing the encfs password int the keyring or "cache password for cron"?

I have indeed been using encfs for one of my backup drives, but the pass is something I enter when starting BiT
