I installed Ubuntu 19.04 and Docker. I'm running some home automation containers on them. Everything was fine and I was happy.
Recently one of my friends modified my user permission allowing me to run Docker without needing to type
sudo docker every time. It worked fine, but yesterday I was trying to install some stuff and I got this error message:
myusername is not in the sudoers file. This incident will be reported.
I looked for solutions, and found that all I have to do is boot into recovery mode and add myself back as a sudo user to sudoers.
I have tried every possible way to boot into recovery mode, but none of them worked including press holding/repeatedly the Shift up/down and Esc keys when booting.
I can boot using Ubuntu live, here is the out put of
Sudo dmidecode t1, running Ubuntu 19.04 on INTEL NUC with USB keyboard.
