kde frontend, ModuleNotFoundError: No module named 'sip'

[ivanto]

[Impact]

usb-creator-kde does not open

:~$ usb-creator-kde
Traceback (most recent call last):
  File "/usr/bin/usb-creator-kde", line 21, in <module>
    import sip
ModuleNotFoundError: No module named 'sip'

[Test Case]

Run usb-creator-kde and make sure it starts as expected.

[Where problems could occur]

Can't think of anything. Right now the application does not start at all, so it's hard to think of how much more it could regress.

This seems to be a simple dependency issue: installing python3-sip packages solved this.

[Ariel Faigon (ariel.faigon)]

Some more info, with the hope this is helpful.

installing python3-sip didn't work for me:

```
% sudo apt install python3-sip
Reading package lists... Done
Building dependency tree
Reading state information... Done
python3-sip is already the newest version (4.19.7+dfsg-1ubuntu0.1).
0 upgraded, 0 newly installed, 0 to remove and 83 not upgraded.

% /usr/bin/usb-creator-kde
Traceback (most recent call last):
  File "/usr/bin/usb-creator-kde", line 21, in <module>
    import sip
ModuleNotFoundError: No module named 'sip'
```

This is because of needing to support multiple `python3` versions:

```
% sudo update-alternatives --config python3
There are 3 choices for the alternative python3 (providing /usr/bin/python3).

  Selection Path Priority Status
------------------------------------------------------------
  0 /usr/bin/python3.8 3 auto mode
  1 /usr/bin/python3.6 1 manual mode
* 2 /usr/bin/python3.7 2 manual mode
  3 /usr/bin/python3.8 3 manual mode
```

Installing `sip` (for the python3.7 env) with `python3 -m pip --user --upgrade sip` (keeping the system python install intact, doesn't solve the problem either). Same import error.

If I edit the shebang line of /usr/bin/usb-creator-kde to the more explicit:

    #!/usr/bin/python3.6

the script starts without failing the import.

However, it fails immediately after with a popup "An error occurred while talking to the udisks service"

    systemctl list-units | grep udisks

shows there's a `udisks2` service but not a `udisks` service.

So yes, this is a simple dependency issue that keeps growing over time.

Issue still exists in hirsute daily builds. usb-creator-kde version 0.3.9. Suggested solution on ubuntu-testers telegram group was to replace line `import sip` in `/usr/bin/usb-creator-kde with line `from PyQt5 import sip`. This fixed the issue for me.

[Brian Murray (brian-murray)]

This bug is being targeted as an SRU for Ubuntu 21.04 and subsequently the bug description could use some SRU information. Please see wiki.ubuntu.com/StableReleaseUpdates for details. Thanks!

[Jan Rathmann (kaiserclaudius)]

For me doing 'apt install python3-sip' solves this too, as darthkhamul wrote in #4.

Hello ivanto, or anyone else affected,

Accepted usb-creator into hirsute-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/usb-creator/0.3.10 in a few hours, and then in the -proposed repository.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-hirsute to verification-done-hirsute. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-hirsute. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!
