Assalamualaikum warahmatullah.
I've just upgraded from
Ubuntu 11.10 Oneiric Ocelot to
Ubuntu 12.04 Precise Pangolin.
For some reasons the system has given me internal errors since the last two start-ups.
My cousin suggested the reason to be the dual-boot thus not everything was upgraded. To try iron out the problems, she suggested updating the system manually using the
Terminal. Then remove unneeded packages using the
Terminal as well.
The command line has changed since
Ubuntu 9.10 Karmic Koala. The old post:
How to update Ubuntu using the Terminal or Update Manager [Ubuntu 9.10 Karmic Koala]
(
http://ubuntudigest.blogspot.com/2010/03/how-to-update-ubuntu-using-terminal-or.html)
I stopped using the
Terminal after i had some problems with the update or something and have been updating using the
Update Manager since. The problem happened some releases back. That's why i haven't update that post although aware of the change in command line. But there's no reason not to make a new post now.
Part A: Update using the Terminal
Pic 1 - The Terminal window.
1. Run the
Terminal window.
i'm used to the
Launcher being auto-hidden in
Ubuntu 11.10 so i had the
Launcher hidden for
Ubuntu 12.04 as well.
In 12.04 - the launcher is not hidden by default.
