Potentially it may have something to do with MFA? I would expect the popup for entering the Microsoft Authenticator App Token, but its not appearing at all.

Hi @wagnst, that segfault looks nasty.

Have you tried cleaning the config folder (check the known issues section), removing the app and installing it again?

If that still the case, can you repeat the previous steps by trying one of the other packaged versions?

Also, can you specify your package? We release in different flavours and each of them has its own peculiarities.

[wagnst]

Yes I tried that already. I removed the .config/teams-for-linux folder, deinstalled the package via dpkg and installed teams-for-linux_0.7.0_amd64.deb again via dpkg. I get the same segfaults.

[IsmaelMartinez]

I can only suggest running from source and start adding more log messages to see where it breaks. It might be the MFA pop up as you suggested, but that is a difficult one for me to test. I leave it open to see if we can help. Keep us posted with your research/investigation (if you can do it). Otherwise, you might need to use the browser until Microsoft releases the Linux client (hopefully soon as they just indicated that they are working on it). Apologies for not being more helpful.

[IsmaelMartinez]

Closing this as it doesn't seem to be much activity on it. Ping back with further information if needed. Apologies but hopefully ms will have a client soon (and I will have more time for my side projects)

FYI @IsmaelMartinez with the latest version it works again... used the latest .deb package under Ubuntu 19...
