[ Tests ]
Installed it locally for several days, without issues.
Did not got any reponse that things are broken.
[ Risks ]
nextcloud-desktop is a leaf package, so no other package can break.
The diff is straight forward and small.
[ Checklist ]
[ x ] all changes are documented in the d/changelog
[ x ] I reviewed all changes and I approve them
[ x ] attach debdiff against the package in testing
