I'm running Linux Mint 17.1 on my old desktop pc. Since I moved, I had no internet connection, but could use the WLAN of my neighbors. For that, I had to install an old FRITZ! USB WLAN driver. I did that by downloading a bunch of required packages via a WLAN capable notebook, copied the deb-files to the pc and installed them via
sudo dpkg -i
Here are the packages that I installed during the offline installation:
and the packages that I additionally installed to solve dependency problems:
The WLAN-driver worked. The problem is, I installed package versions, that are newer than the current Ubuntu packages. Since then, I can't get updates anymore due to a broken package (libgcc1).
Now, I have a wired LAN connection again and I want to fix the problem. When I run
sudo apt-get install -f
apt wants to remove a bunch of packages and I get the message "You are about to do something potentially harmful"... This is not what I want to do ;)
All I want to do is to get my old system back, which means all packages in the current Ubuntu version (trusty-updates). How can I achieve this?
