The Ctrl – C / Ctrl – V copy / paste classic commands do not work in the Gnome-Terminal.
In the Gnome-Terminal, Ctrl – C terminates the process, while Ctrl – V is interpreted different by the shell. I recommand you not to edit the Ctrl – C and Ctrl – V shortcuts, learn the new ones instead.
How to copy paste in and from the Gnome-Terminal:
1. Ctrl – Shift – C and Ctrl – Shift – V :
Ctrl – Shift – C copies the selected text in the terminal.
Ctrl – Shift – V pastes the copied text in the terminal
There is also a pair of keyboard combinations that do copy paste:
2. Ctrl – Ins and Shift – Ins :
Ctrl – Ins copies the selected text in the terminal
Shift – Ins pastes the selected text in the terminal, even if you haven’t copied it.
