Question

I installed Ubuntu in the wrong language (Italian) and cannot switch to English.

I tried switching by the settings app but I still get parts of the terminal etc. in Italian. Is there any way I can fix it without reinstalling my OS?

1. Localization

   sudo apt install language-pack-en

3. locales

sudo locale-gen en_US
