Couldn't load SIP module (Python in QGIS)

[Thiago_Dietrich]

Hi,

I’m a lay user on Linux systems. My QGIS program suddenly stopped recognizing/loading the SIP module, so it stopped reading in Python and lost its main functions. That’s the initial message

One of the commands I tried was pip3 install PyQt5-sip, where the return message was Requirement already satisfied: PyQt5-sip in /var/local/lib/python3.7/dist-packages (12.8.1) [free translation from portuguese], but the file does not exist and the problem continues.

Another command, pip3 install sip, returns:
unable to run ‘x86_64-linux-gnu-gcc’: file or directory does not exist
error: command ‘x86_64-linux-gnu-gcc’ failed with exit status 1
[free translation from portuguese]

I really need to use the program in my work and I wouldn’t like to migrate to Windows just for that reason. Can anyone help?

Thanks for understanding my bad english.

Something that would help us a lot to understand the problem would be this:

1. Open the application called ‘Terminal’
2. In this application run the command:

eos-diagnostics

3. The above command will create a file with the information of your system (example: eos-diagnostic-160614_111731_UTC + 0100.txt); Send us this file so we can analyze and see a possible solution

The command didn’t create a file. The answer:

** (org.gnome.Nautilus:10830): WARNING **: 20:02:08.773: Error on getting connection: Failed to load SPARQL backend: Cannot autolaunch D-Bus without X11 $DISPLAY

From this discussion: https://github.com/flathub/org.qgis.qgis/issues/74
It seems to be a module naming issue here, and it is under fixing.

If you can’t wait for the next update, you can try rollback to a previous working version with following command, open a Terminal copy paste this text and hit enter:

$ sudo flatpak update --commit=b3333b5244bc94902b54f1f0e5d8013a6401e8ef60f191d97dc9c27f54378db8 org.qgis.qgis

Then reopen QGIS.

Let us know if this works for you.

Yes. This worked! Man, you rock! Thank you very much.
