I found the same problem with the language setup on Ubuntu 17.10. This could be related to the new Gnome Settings (just let me know if you think I should open a new bug report).
I was running Ubuntu 17.10 in Italian language, previously installed with the old Gnome Settings. I wanted to switch to English language but I couldn't because of this bug. Following the steps of the bug description, the only difference was the terminal warning: "Language it_IT not installed, trying to install it" ..which is a bit strange because the system was already set to Italian, I wanted to set the en_US.UTF-8. I've noticed that while trying to change the language settings, the strings in /etc/default/locale don't change at all. :::::: WORKAROUND 1- sudo nano /etc/default/locale 2- Comment or delete the existing strings end write the following: LANG="en_US.UTF-8" LANGUAGE="en" If I want to go back to the Italian setup I just need to write the following: LANG="it_IT.UTF-8" LANGUAGE="it:en" 3- Press [Ctrl]+O and [Enter] to save the file. Press then [Ctrl]+X to exit from Nano editor. 4- Log-out and log-in again or restart the system. After the log-in the system is asking if you would like to update the names of the folders into $HOME (Desktop, Music, Video, etc..). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1631750 Title: Language installation doesn't work in Ubuntu GNOME 16.10 Settings app To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-gnome/+bug/1631750/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
