I'm relatively new to Ubuntu and was just trying to install CMake. I'm running Ubuntu 18.04.
I followed this tutorial:
and the system immediately began acting strangely. Using cmake --version declared that cmake was installed incorrectly. The Left panel disappeared and many icons went missing. Basic functionality in any window currently open was then malfunctioning. I logged out with Ctrl+Alt+Del and the screen froze causing me to force shutdown the system by holding the power button.
Using this shell, I also navigated to where the files from the cmake install tutorial should have been moved to. However, they don't seem to exist.
I would really appreciate if somebody can help me reverse what I have done and also give me insight into why the actions I took in this tutorial broke the system. Possibly the directories are different between 16 and 18?
I have a lot of files on this system and want to avoid a reinstall at all costs.
