Sudo apt autoremove made a mess

@Aravisian

Yes, it looks like a space between to me, too.
But looking in the "read More" of the description, there is no space visible, there. I think it has to do with how it appears on the video screen.
You clearly followed that very carefully, based on what you could say. And very good that you have backups.

You're right. I didn't "read more", just made myself focused on the video.

@Aravisian

But in future, remember that any command that follows any direct path must have a Full path in order to complete its run of that path.
In the case of a 'rm -rf', this can get dangerous; As white space left behind can halt the path too soon.
In this case, the path halted at your Home Directory instead of at the ~/.cache/opera directory.

Okay, I'll bear it in mind. Thanks again, I really appreciated your willingness to help me. And, of course, many thanks to others who jumped in this topic.

Well, when I second thought, I myself made a mess not only of my machine, but this topic too. Sorry, I suppose this is what the first steps of an inexperienced Linux user look like.

Or of a Linux user. We all make messes of our machine and of topics.
@swarfendor437 can attest to the multiple times I nuclear bombed my machine early on, trying out all sorts of crazy things.

Sometimes crashing a machine is how we learn things. If it is not a production machine i.e., used for day to day work, then it does not matter - it is all part of the fun of learning GNU/Linux. At least you can do things with GNU/Linux - your hands are not tied to proprietary licences that Microsoft and Apple use - you own the Operating System it is yours and it is what Community is all about!

@swarfendor437

you own the Operating System it is yours

That scares me.

[swarfendor437]

You should be more scared of what is contained in M$ and Apple EULA's!
As the motto of our Linux User Group here in my city states: "Friends don't let friends run Windows."

[budjojed]

Just joking. No more Windows any more! I'm simply not used to Linux Terminal, barely know anything about commands.
