Same here. 64 bit install, 10.10. Initially failed to even attempt
upgrade via update manager (no internet connection despite having just
upgraded existing packages via the same connection). Then got a bit
window saying the update was available. This was more successful, and
downloaded everything
Addendum: Interestingly package manager is now claiming I have 788
updates to apply (was all up to date prior to the attempted 11 upgrade
last night), but also claims it can only do a partial update, possibly
due to a previous upgrade which didn't complete... I thought it would
not upgrade
