Some time ago I installed Brave but I didn't like it, so I removed it with
sudo apt-get remove --purge brave-browser. After some time I had to reinstall it because I needed a Chromium-based browser. As soon as I opened it it asked be to redeem my old BATs, so I deduce that apt-get left something in my system.
Now I don't need Brave anymore and I'm wondering how to remove it completely. I would use
sudo apt-get remove --purge brave-browser once more but it looks like it doesn't really remove everything - what command should I use instead?
