i now have my new laptop working with ubuntu after the tec person
at the place where i do voluntary work for altered the cd rom in
the bios settings for me.
i am told that when i upgrde from one version of ubuntu to
another i dont need to do a fresh install.
however i can't seem to be able to upgrade one version of ubuntu
desktop to another via the command line.
i have had a look at the update manager which is less accessible
when it comes to upgrading.
it seems to work with updates but for some reason my upgrades via
update manager don't appear to start or it doesn't do it properly
for for some reason.
i have tried the alt f2 update-manager dash d command and i get
told there is an upgrade, i press the upgrade button with enter
or space, i am then asked for my password which i type and i
enter or space on the ok button but i am wondering if there is
another upgrade button which i cannot locate with orca which i
need to hit to actually get my upgrade like it is asking "are you
sure you are sure you want to carry out the upgrade" which it
doesn't appear to do when you do an update because all you do is
if it shows check boxes for the updates when it enters update
manager you just hit the install, maybe type your password and ok
it and away it goes.
if i remember correctly when i tried looking at the update
manager in vox bar and accepted my upgrade, ben appeared to
suggest that the upgrade hadn't started and that he told me to do
a tab or a few tabs to get to a button which orca doesn't read
marked upgrade to actually start it which is why i am having a
problem with doing it without having a pair of eyes handy.
someone suggested i type sudo do-release-upgrade from the
terminal and it was like it was trying to do an upgrade, i was
asked if i wanted to install the upgrades although i got some
error message about mirrors something like "unable to use default
mirror" or something along that line before i was asked if i
wanted to do the upgrade and that i was told it would take 6
hours to do it, i pressed y to accept and enter and it started
the upgrade or so i thought and then part way through i lost
speech altogether, after leaving the system for the recommended 6
hours i had no speech and had to switch off the laptop so i don't
think it installed properly if it was doing the upgrade as ctrl
alt delete wouldn't work.
that is the furthest i have ever got with ano upgrade.
my guess is the problem was that i was downloading the server
version instead of the desktop version but i can't be sure.
i am not even sure if there should have been a message warning me
about reading the mirror which it came up with when checking
against my version so i still don't know how i know when i have
been successful so it looks like me having to do a clean install
every time i decide to get a newer version of ubuntu.
