which of these 2 did do:

sudo apt-get dist-upgrade apt-get dist-upgrade? 

i'd dare user doesn't have correct permissions. receive similar shorter output if run without sudo.

open terminal , type

groups 

what output get?

the links posted might have answer without being direct answer.

the third link contained link directions on how remove lock on file answer removing lock

one of other links specified having open program touches file causes locked begin with. have made sure there isn't update process launching default when turn on pc? i'd make sure don't have update process starting , reboot , try again. rebooting kill program , if doesn't auto-start, lock should gone , therefore problem should not persist.
