openconnect-sso 0.6.2 requires structlog<21.0,>=20.1, but you have structlog 21.1.0 which is incompatible.

I tried going back to stuctlog-20.1, this threw another error. I thought it be good to post this as an issue.

During handling of the above exception, another exception occurred:

Works for me with pip install structlog==20.2.0. I'm running archlinux with 5.10.16-arch1-1 kernel. If I had used the pipx way of installing instead of the archlinux aur package, maybe this issue would not have happened in the first place? :thinking:

Thanks to the team, openconnect-sso has really made my life easier the past few weeks :muscle:

pipx creates an isolated environment for openconnect-sso, so it won't break due to changing system dependencies.

The AUR package, however, depends on Python packages that are coming from the official repositories of Arch Linux (for example, https://archlinux.org/packages/community/any/python-structlog/), so it might break after a system upgrade. I'm trying my best to keep the AUR package up-to-date.

[vlaci]

We could maybe relax version constraints on the dependencies and do an automated dependency update if tests pass :thinking:

[vlaci]

Fixed by #44

[MrAnno]

@vlaci That sounds awesome.

I'm getting errors again on arch linux. Would it be possible to change the dependency from:

structlog<21.2.0,>=20.1

to something like:

structlog>=20.1

From the other tickets it says that the version is just date based and not semantic so a rule to stop an update to the 22 version that will come out in a few months isn't really needed imho.

I fixed my setup for now by downgrading python-structlog to 21.1.0-1 but it would be nice to be able to keep track with arch updates.
