Problem with gedit

  • 772

I am using ubuntu 16.04 LTS.
gedit does not start when I type in the terminal:

gedit

I do get the following error:

(gedit:9955): GLib-GIO-ERROR **: Settings schema 'org.gnome.gedit.preferences.ui' does not contain a key named 'notebook-show-tabs-mode' Trace/breakpoint trap (core dumped)

I googled this but nothing fixed the problem (I tried to remove then install it...etc)

When I run:

apt-cache policy gedit

I do get:

gedit:
Installed: 3.18.3.is.really.3.10.4-0ubuntu13

    For some reason, you installed gedit from an obscure ppa (called ppa:mc3man/older), instead of from the official repositories.

    First, remove the references to the ppa. The easiest way to do that is to install a program called ppa-purge:

    sudo apt install ppa-purge

    then use it to remove the offending ppa:

    sudo ppa-purge ppa:mc3man/older

    Then the package sources need to be updated:

    sudo apt update

    and the official gedit can be installed:

    sudo apt install --reinstall gedit

    Done. The last two commands will now probably succeed, so I combined them into one line using the && directive. This means: do the first command, then if successful, do the second command.

    sudo apt update && sudo apt install --reinstall gedit
