Ubuntu – Warnings while launching gedit from the Ubuntu terminal

command linegedit

I am facing these warnings while launching gedit from my terminal. Eventually gedit starts, but with these lines of warning every time when I launch gedit:

Updating gir1.2-gtksource-3.0 solved the problem for me; the errors no longer appear.
