I have old Linux kernel versions that I don't use so I was trying to remove them.
List of installed kernels from dpkg --list | grep linux-image
linux-image-5.4.0-26-generic (5.4.0-26.30)
linux-image-5.4.0-33-generic (5.4.0-33.37)
linux-image-5.4.0-37-generic (5.4.0-37.41)
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?
How do I remove snap? apt pretends it's not there, but I can still call commands with it.
Trying to remove it says read only file system

I installed zsh, but I realized I miss the basic/default terminal look. How can I get back to the default shell?
I have messed up my Ruby dev environment on Ubuntu 10.04.
What is the best possible way to remove these packages from my system?
To start fresh, I would like to re-install Ruby using RVM.
