How do I install bitwig? [duplicate]
Solution 1:
Your syntax is incorrect.
If you downloaded a .deb from the internet and you wish to install it with apt, you must cd to the directory where the .deb file is located.
Then you need to run sudo apt install ./yourdebfile.deb.
You should run sudo apt update before any other commands in apt to make sure that your package manager is up-to-date with the most current list of software. Otherwise you can encounter dependency issues.
Note that the . must go before the /.
