Until your shit got all fucked up because you added a third party repository. And then you have to manually remove lock files and fix the pkg database and mess with .conf files and manually uninstall specific versions of dependent packages, and then manually re-enable some remote repo.
Then you actually kind of do feel like a hacker.
Until youβve done it like 10 different times, then you are just annoyed. Still a better love story than Twilight.
You copy paste the command.
Your distro doesn't set up/install
sudoby default, so your first task is installingsudo, then understanding /etc/sudoers syntax and understanding why the command to atomically replace /etc/sudoers isvisudoand why on a multiuser system there's value to atomic replacement. In the meantime, you probably learn aboutsuand maybe, if your distro has disabled them, how to enable switching to the kernel virtual consoles on tty1 through tty7 so that in the meantime, you can do things as root while staying logged in. Also, you're going to learn about environment variables, so as to set EDITOR, and where your shell config files live, what a login shell is, and in what shells ~/.bash_profile, ~/.profile, and ~/.bashrc run. Also, you first try running visudo as a regular user, but your distro placesvisudoin /usr/sbin instead of /usr/bin, so you can't figure out why it's not installed and are going to learn about the FHS and mlocate andupdatedbso that you can find /usr/sbin/visudo anddpkg -Sso that you can figure out which package it's in and confirm that it's actually installed and learn about PATH.This fucking idiot here changed their debian branch to sid then wondered why the software store didnt work. Luckly I always backup config files. I mean, it's not that complicated to change some lines back, but still.
Also it's a vbox vm so I could always restore a snapshot. And it exists to tweak so it was meant to be.
Dependency hell is always, always, self-inflicted.
aptis only SLSA1 or 2 anyway, so there's a lot more wiggle room.
