How to add myself to sudoers when accidently remove main user out of the sudo group

Question

I was trying to create a public and private share directory using samba and I ended up accidently relocated my main user to smbshare group and can no longer use sudo commands or log in as root. I will not be able to get into recovery mode.

Answer 1

You will need to boot into recovery mode, mount your filesystem and edit the /etc/sudoers file. You can also do similar from live media.
