This guide is for system adminitrators (sysadmins). Make sure to follow it and you might no screw up everything. Most of the points are after real events i've gone trough. They were stressfull. I'm writing this in good faith and in belief it'll help me and you.
- When your boss tells you that production is down go here
- Allways try installing software with a software manager, snap, apt, pacman, yay,... really doesen't matter. In fact try ALL of them first
- don't develop on production server
- don't eddit sudoers file if you don't know exactly what are you doing
- don't edit .ssh permissions, definetly don't set them to 777
