Luke,
what will happen if i will run the Linux version and then switch back to the ppa version, will the wallet will sync properly?
It should, but there's no point.
Well, as for the openssl, what i did is this :
aptitude show libssl1.0.0 | grep Version
and it show this-
Version: 1.0.1-4ubuntu5.12
which seems to be the latest for ubuntu 12.04 LTS
I am still not sure i am protected..
