Try to re-run the command

Change the version to "netcoreapp3.1" then it will work . I have complained to qwiklabs support numerous time  but they don't really care about this so just change this and it'll work.

[Abhishek213]

[rokde_himanshu]

[Kirlosik]

Maybe you know how to deal with an error:

/bin /bash: ffmpeg: command not found?

[Abhishek213]

Yes u haven't installed this try to rerun it on terminal

[Kirlosik]

Actually, I did install it

[Richard_Rivero]

I got the same problem but in the terminal there is a sudo option to reinstall dpkg package

[Kirlosik]

could you please share a screenshot with the execution of the code in the terminal?

[harshit1921]

Wait 5 - 10 minutes after jupyter notebook has started then run the install command . It will install ffmpeg then 

[Kirlosik]

Can’t track the progress anymore in that lab, even though Jupyter notebook Is successfully running.
