Okay, I appreciate your warning about "kill -9 ..." but what should I
have done to stop the "apt" process or any other process as far as that
goes? There are many reasons why it may be necessary to stop a process.
I obviously don't know the best way. For just one example, when using
FireFox web browser to capture web pages I have seen it hang Ubuntu
because of some conflict with a media player that is not responding or
does not exist. Sometimes I have had to crash Ubuntu because of these
sorts of things but most of the time I can use the command line in
another desktop window to kill the FireFox web browser as the system
quickly slows into a hung mode. However, I would appreciate some good
advice on this subject of dealing with these kinds of problems. There
has to be a better way to break a hung system (non responsive) other
than crashing that system.
I have tried to deal with such hangs by using another machine to
remotely access the non responsive machine. Connection is slow but
eventually I can access the non responsive machine. However, the
commands I give the non responsive machine by this means are disregarded
I think because the "sudo" command cannot be passed by this means.
Also, given what I said above what upgrades will occur if I use the
"sudo apt-get update && sudo apt-get
install ubuntustudio-desktop ubuntustudio-audio
ubuntustudio-audio-plugins ubuntustudio-graphics ubuntustudio-video
linux-rt" and will the servers and/or kernel be changed???
