Hi!
The current nextcloud-desktop package version in Debian bookworm/12.2
shows two-factor authentication notifications, but does not list them in
the main dialog window - so a user cannot approve or deny them.
This renders it unusable for two-factor authentication, requiring the
user to have a logged-in Nextcloud client on a different system to
approve their browser logins.
This has been fixed upstream in v3.8.0:
https://github.com/nextcloud/desktop/pull/5486/commits/ec7b5481d45f89bccbe2fc7cb8cd0548452c8729
Debian testing's previous nextcloud-desktop package version, 3.9.0-1,
had this working and was installable on bookworm without impacting
non-Nextcloud packages.
The current package version in testing, 3.10.0-1, however, depends on
versions of libstdc++6 and its dependency gcc-13-base from testing.
Cheers,
Luban
