Thanks! Soon after installing Ubuntu, I had disabled the updates (by setting it to use only security updates, see attachment picture).
I did not know that changing that would change my system sources. I changed it back to `All updates` and now I was able to install `libglib2.0-dev` ``` $ sudo apt-get install nemo Reading package lists... Done Building dependency tree Reading state information...
