Yup, I did all that,got frustrated and reinstalled the OS.
1. checked that etc/apt/sources.list was not commented out
2. sudo apt-get update
3. sudo apt-get install gedit-common gedit gedit-plugins
process ran exited with no errors or warnings and I now have gedit installed and working.
Now all I have to do is update linuxcnc with the master,
What I did last time is use the LinuxCNC buildbot instructions
buildbot.linuxcnc.org
I think that that is where all my troubles started. I maybe put something where it was not supposed to go.????
short version
get a key
get the master stanza into etc/apt/sources.list.d/linuxcnc-buildot.list
sudo apt-get update
sudo apt-get install linuxcnc
any glaring errors to this. Maybe I put stuff in the wrong place. When I did it I uncommented the entry for the master list and commented the other entries.(good or bad)?
Have not done that yet. As i said I did something stuped.
