[P .NIKOLIC]

Hi folks

Having been in hospital for a while i updated this system a couple of
days ago and am having some strange problems 


If i run  pacman -Syu   i get 
7-of-9:/ # pacman -Syu
:: Synchronising package databases...
error: failed to update core (unable to lock database)
error: failed to update extra (unable to lock database)
error: failed to update community (unable to lock database)
error: failed to update multilib (unable to lock database)
error: failed to synchronise any databases
error: failed to init transaction (unable to lock database)
error: could not lock database: Read-only file system

mount gives
