To Reproduce
Steps to reproduce the behavior:

1. start ikhal
2. hit 'n' to add new event, enter anything in event title and save

Expected behavior
Event added, ikhal doesn't crash

OS, version, khal version and how you installed it:

• The output of khal --version: ikhal, version 0.11.3
• Installation method [e.g. PyPI, git, OS repo]: distro repo
• python version [e.g. python 3.9]: 3.12
• OS [e.g. arch]: Alpine Linux (edge)
• Your khal config file
• The versions of your other python packages [e.g. the output of pip freeze]

Additional context

This is due to a breaking change in icalendar and should be fixed by #1364.

[craftyguy]

@d7415 thanks for the pointer. I backported the functional part of that series to 0.11.3 and confirmed that it fixes this and #1366

I'm in 0.11.3 but I got the same error: which version of khal shall I install to be able to add new events?

(I'm using vdirsyncer: perhaps I should rather downgrade vdirsyncer? Do you know to which version?)

Thanks!

I'm in 0.11.3 but I got the same error: which version of khal shall I install to be able to add new events?

#1364 is needed to address that but it is not merged so no releases contain that fix at the moment.

(I'm using vdirsyncer: perhaps I should rather downgrade vdirsyncer? Do you know to which version?)

vdirsyncer is unrelated. It depends on icalendar Python package. If you can downgrade icalendar to a 5.x version it should avoid that problem.

[cerisara]

OK, it indeed works with ``` pip install icalendar==5.0.13 ``` Thanks! Le Sat, Nov 30, 2024 at 01:53:35AM -0800, Leonardo Taccari a écrit :

Hey, i tried to fix it on #1374 (comment)

[micheldebree]

I just installed khal for the first time today to try it out. Adding a new event already failed on this error.
Installed with brew install khal
Does this mean khal is not really supported for macOS homebrew users?
Is there a workaround?

[nbbaier]

Like @micheldebree I also installed through brew and am facing this issue. Any update?
