How to reinstall packages without internet connection

[C1ph3r1324]

I had a problem a few weeks ago where installing mono (C# ide for linux) caused the GUI to fail to start and all drivers related to internet also failed. Xorg commands caused a crash and Xorg -configure gave me a message that was very strange... "more monitors than devices" error popped up...

Is it possible to, "repair" kali linux by reinstalling packages from a USB? If so, how do you do so?

Hi C1ph3r1324

To be honest, I don't know if you can "repair" your kali installation, but if I was you I could try this:

All the packages you downloaded are stored in /var/cache/apt/archives. From another machine, or a live kali you can install debsums. (debsums - check the MD5 sums of installed Debian packages)
It will be stored in /var/cache/apt/archives/debsums_2.0.52_all.deb

Copy and install debsums to your broken machine and run it with --changed option which will only list modified files or with --config it will verify only the configuration files.

If (you will ) find any broken files, you can identify them to which deb package they belong by running:

dpkg --search /path/to/your/broken/file

Now, you can reinstall the broken package by executing:

apt-get --reinstall install broken_package_name

Good luck!
