greetings . . .

i've about concluded that i absolutely must upgrade my linux/tde install. 
i'm currently running 14.04 atop ubuntu 1204-LTS, which is at its end. 
hypothetically i should be able to do use ubuntu's system upgrade tool and 
all would be well in moving me from 1204 to 1404; i would not have to 
reinstall everything from scratch. but no. it throws this error:

Could not calculate the upgrade

An 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

looking in /var/log/dist-upgrade, i find this error:

[quote

ERROR Dist-upgrade failed: 'The package 'kubuntu-desktop-trinity' is marked 
for removal but it is in the removal blacklist.'

[/quote]

for some reason i must have added it to that blacklist, but truth be known 
i do not remember having done so or even the existence of such a 
blacklist, never mind how to add or delete something to or from it.

so, am wondering if there is a way around this that wouldn't (as it appears 
would happen here anyway) nuke my TDE install.

am i missing something obvious? do i want to d/l and install a TDE image 
and, if so, can i do an upgrade (rather than wipe and reinstall) from 
that?

thanks in advance
