How to get critical [default?] packages back

[Prescience500]

I have a rather unique problem. I wanted to try out pcsx2 to see if i could get my games to run at higher quality than on my actual PS2. I installed it via muon package manager (what can i say, i prefer it). Unfortunately, the app crashes every time I tried to boot it.

Naturally, I uninstalled it to save on memory. For some reason, muon simply went nuts and started uninstalling lots of critical packages in addition to pcsx2. I'm not sure what all is gone, but i'm afraid to reboot, turn my computer off, or do anything else that might clear my ram because I'm afraid of not being able to get KDE to boot again. Chunks of plasma seem to be gone (like titlebars and certain icons) and I'm not sure what all is now missing. How can I safely get those system packages back when I don't know what is now missing?

Any help is greatly appreciated. Btw, I'm not sure if any critical packages are missing relating to X, the kernel, etc.

One of the things which makes GNU/Linux a great operating system is that virtually anything and everything happening on and to the system may be logged in some manner...

apt logs: /var/log/apt/history.log
dpkg logs: /var/log/dpkg.log


Update Logs: https://www.kubuntuforums.net/showth...36-Update-Logs

List of (recent) removed packages:

grep remove /var/log/dpkg.log

Just re-install the "kubuntu-desktop".

sudo apt-get --reinstall kubuntu-desktop

Just re-install the "kubuntu-desktop".

sudo apt-get --reinstall kubuntu-desktop

This should give you back everything that is installed on the default install...although the proper syntax of the command is:

sudo apt-get --reinstall install kubuntu-desktop

But you should also check the logs (pointed out by LinkBot) for any removal of packages you've personally installed on top of the "default install".

sudo apt-get --reinstall install kubuntu-desktop

Hummm I always thought it was

sudo apt-get install --reinstall <package>

and dose work in this syntax.

Either way works.

[vinnywright]

Either way works.

indeed ,,,,BUT , when talking "proper syntax" ,,,, I believe the main option comes first (install) then a "-" or "--" switch or modifier to the main option.

Well, yes, but this is Linux; you aren't (necessarily) constrained to just one option.

If you look at the man page of apt-get, it shows the syntax as: "apt-get [options] {command}", which technically means "apt-get --reinstall install", but either way works...the important thing is including the {command} part (install). (Still, I'd recommend getting into the habit of following the man page syntaxes of commands, as some commands are pickier than apt-get about the correct syntax)

Thanks for catching that Kubicle!

I stand corrected ,,,,,the man page dose state this .

it just seems backwards to me still however .
