[jammy] spyder does not start because of kite install widget

I confirm this bug exists, the workaround is pretty easy you have to (int) the returned values in several files, patch following soon... hint from: https://github.com/spyder-ide/spyder/pull/16574

Status changed to 'Confirmed' because the bug affects multiple users.

https://sid.ethz.ch/return.patch

cd /usr/lib/python3/dist-packages/spyder/
patch -p1 < /home/you/return.patch

Confirmed on fresh install of Ubuntu MATE 22.04 LTS.

Who is really responsible with releasing broken Spyder3 on the LTS system to be used for next 5-10 years?

Please prepare SRU instantly!!!1111

Thanks for the patch, it also works for me. It would be great if the package could be updated soon.

I added a member of the 'Debian Science Team' that are listed as maintainers of the package, so that they may hopefully help us get the fix pushed out.

Spyder 4.1.2 is broken in several other ways, too:
It keeps occasionally crashing with this issue:

Still no update of the package though the patch has been here already for four months? It is a bit sad that I have to tell my students when introducing Python and Linux to not use Ubuntu 22.04 because I cannot expect them to manually patch packages if they're new to Linux. :(

Spyder is updated in the Ubuntu 22.10. (version 5.3.2) and works if you update the system.

If you install the new version, everything seems to work.
Because Ubuntu 22.04 is a LTS version, one can expect the spyder package will be backported soon. Probably, you can install this new version on Ubuntu 22.04, but I did not try.

patch works thank you

Nevermind, i hoped they would have fixed the code in the repo by now...

Confirming the bug, spyder 4.2.1 does not start in 22.04.2:

Patching with return.patch from #6 helps. But it would be great if that wouldn't be necessary.
