fprintd: Failed to start Tudor host process <...> NoReply: Remote peer disconnected

[VeryEvilHumna]

I have 06cb:00be and experienced the same issue as described in #35. After 1d08e98 commit is made I git-pulled the repo and tried to reinstall everything as described in readme.

My environment is ThinkPad L15 Gen 1 with Fedora 41, libfprint-tod is from quantt corp repo

dnf list:

Also, unrelated, but ninja install script moves libtudor_tod.so to /usr/local/lib64/<...>, but libfprint-tod checks /usr/lib64/<...>, so I moved libtudor_tod.so to /usr/lib64/libfprint-2/tod-1/, maybe install script needs a fix

Update: I tried the solution from #14 (and did a restart), unfortunately, it didn't help

[Popax21]

It seems like the host launcher is failing to claim its D-Bus name, which causes communication issues. This might be because of it being unable to claim the name (maybe the D-Bus policy isn't picked up?), or maybe there being conflicting claims.
Can you try completely uninstalling synaTudor, then reinstalling it?

[VeryEvilHumna]

Thank you for your answer, sorry for answering late.

I tried to reinstall with recompiling, but it unfortunately hadn't changed situation at all :(

Log from terminal (no errors, everything looks perfectly fine)

Does it work if you start tudor-host-launcher yourself (by running sudo systemctl start tudor-host-launcher)? I suspect that a faulty D-Bus configuration file might cause it to attempt to start twice, which could cause contention over which instance is able to successfully claim the name.

Unfortunately, it still doesn't. Tried to start services in different order of steps, nothing helps

➜  ~ fprintd-enroll
Impossible to enroll: GDBus.Error:net.reactivated.Fprint.Error.NoSuchDevice: No devices available

[papuruth]

On my system I'm unable to start the fprintd.service it stays stuck for sometime then fails with error Timed out failed to start service
What I noticed is that if I remove the official libfprint package intalled by fprintd this issues happens

No matter even if libfprint-tod or libfprint-tod-git is installed

It seems that fprintd is dependent on libfprint but its unable to detect either libfprint-tod or libfprint-tod-git

Also whenever the fprintd.service is running when official libfprint is installed and I try to enroll finger I get the following error.

$ sudo fprintd-enroll 
Impossible to enroll: GDBus.Error:net.reactivated.Fprint.Error.NoSuchDevice: No devices available
