Thank you for fixing that failing build, pushed as
27eb4ac9f506f9f06061d79548de5da53ac03bfa.

If you want to update it to it's latestet version, don't forget to run "guix
lint" on it and add your copyright to the file if it's a non trivial change.

Cheers,

Hello Guix,

nextcloud-client has been broken in recent updates to guix and is no longer 
building:

https://ci.guix.gnu.org/build/238676/details

All the errors are in the form of

They see to be directly related to an issue patched in more recent versions of 
Nextcloud Desktop:
