I am on Ubuntu 20.04. Whenever I try to boot up my computer I get nothing only black screen. If I press ESC, then I can see only /dev/sda2 clean, etc. Nothing else. It looks like there is no GUI on it.
I pressed CtrlAltf5 to enter a tty and logged in. Now when I try to install a GUI I get dependencies error. But when I install something else it was doing fine, e.g.,
Aptitude: sudo apt install aptitude was just installed without any error.
The exact error message while installing gnome was:
depend on gnome-setting-daemon (>= 3.24) but it's not going to be installed.
depend on gnome-shell (>= 3.19.92) but it's not going to be installed.
I don't know why I cannot I install gnome.
