Uninstall anbox on ubuntu 20.04

After unsuccessfully trying to make anbox work on ubuntu 20.04, I tried to purge it and start from scratch, but after executing sudo snap remove anbox anbox seems to be still installed and doing find / -iname \*anbox\* gives me a long list of files containing anbox.

Trying sudo snap remove anbox again tells me that anbox is not installed. So what did I do wrong and how can I fix it?

Solution 1:

Once the snap is removed, you have to remove the installed kernel modules as well with the following commands:

sudo apt install ppa-purge
sudo ppa-purge ppa:morphis/anbox-support

Once done, Anbox is removed from your system.

Solution 2:

If you install anbox using 'apt' command, Try to use this command: "sudo apt remove anbox"
