How to Set up MS Teams on Ubuntu 19.10

edit

A simple two step process:

Run the following commands in your terminal:

wget https://packages.microsoft.com/repos/ms-teams/pool/main/t/teams/teams1.3.00.5153amd64.deb

(can also directly download the above file)

sudo apt install ./teams1.3.00.5153amd64.deb

run it in your terminal

sudo apt update

then install snapd (if you dont have)

sudo apt install snapd

now install MS teams

sudo snap install teams-for-linux

this should work, if not, let me know

By the way, I believe you should upgrade to Ubuntu 20.04 LTS since 19.10 is not a stable version, and you might face several issues with it!

Edit : This seems to be a bug which was fixed sometime back(see here), probably upgrading your MS Teams version would solve the issue as mentioned in the other answer.

1) Try updating the teams app.

2)If you already have some other account on it. Try this -- Click on "enter pin smartcard" something like that option. This will "restart" the app. You can try find any other way of restarting the app as well. And then try filling in the details (which will then redirect to SSO page).

3)If not anything above, delete the application and install it again via a different method than it was done before. If earlier you used "sudo dpkg -i..." then this time use the software installer tool to install it (by clicking on the .deb file)
