Spooky's questions

Background information / previous post available here: Need to try to install a specific package version -- however apt-cache madison, apt-cache policy only seem to list the latest version, though I don't think it'll be particularly necessary or helpful to read.

I was trying to run rdiff-backup, which failed as shown here. The issue seems to be that Security Onion (I'm told) runs on an older version of Ubuntu, limiting it's rdiff-backup version / repo available to 1.2.8, whereas the latest version of Ubuntu is running 2.0.0 (if I recall the exact version number correctly, which I think I do.)

Now I pretty much got the answers I was hoping for as far as playing with apt-get install and being able to download a specific version -- but somebody recommended I post this as it's own question, so I wanted to follow suit in case it yielded any helpful answers.

As of now, my workaround is just to install an older Ubuntu version; since for my strictly homework purposes, it doesn't matter what OS I rdiff-backup to, just that I backup to a different box with it.

Other SE posts, for example this, show how you can install a specific package version. However, I'm unsure what exactly the naming convention / syntax used for the version I want is.

I need to install rdiff-backup version 1.2.8, but I'm unclear from looking through github (I'm a noob) what the full package version would be called. Edit: I should note that I did try the syntax of,

sudo apt-get install rdiff-backup=1.2.8

as well as

sudo apt-get install rdiff-backup=1.2.8-1ubuntu1 \

(the latter just blindly copying the syntax shown in the linked example, in the off chance it worked.)

And as the title states, the commands I've looked up that people say should list all or old versions of packages don't seem to work as intended (or as I understand them).

Thanks for your time.

I managed to zoom out with some weird gesture of the mouse and keyboard by accident. No matter what I do I can't figure out how to zoom back in with qBittorrent. It's unreadable as is.

Edit: It's also apparently only on my secondary monitor. Dragging it to the primary shows it zoomed as default. So confusing.

I've also now run rm -r on the ~/.config/qBittorent files in order to theoretically clear any settings, then uninstalled/reinstalled, so it must be Ubuntu causing the window to be zoomed out so far.
