If you have problem running the wallet, open the terminal, add new repo and upgrade your libraries simply by copy-pasting this (line by line):
sudo add-apt-repository ppa:boost-latest/ppa
sudo apt-get update
sudo apt-get install libboost1.55-all-dev
Or install it other way you prefer :)
Why and what for? Simple: some newer wallets must use the newer libraries.
Website for unix-like, *nix or so called Linux users. You don't know how or can't compile the wallet to your favourite cryptocurrency? Try this! Precompiled binaries for 64 and 32-bit. 100% safe.
