hi,
i've been trying to install some upgrades for the last few days but every time i attempt it I get this message
Not all updates can be installed
Run a partial upgrade, to install as many updates as possible.
This can be caused by: a previous upgrade which didn't complete problems with some of the installed software unofficial software packages not provided by ubuntu normal changes of a pre release version of ubuntu
so i attempt a partial install and get this message
Could not calculate the upgrade
A unresolvable problem occurred while calculating the upgrade.
This can be caused by: * Upgrading to a pre-release version of Ubuntu * Running the current pre-release version of Ubuntu * Unofficial software packages not provided by Ubuntu
This is most likely a transient problem, please try again later
and that's that: I'm not allowed to uprade
this isn't really a pressing issue, more wondering whether I actually need to update the software (seeing as the update thing keeps turning up)
any advice?
