Some week ago I have try to update the version of my Ubuntu Linux.
Everything was fine, but at some point the upgrade is blocked......
W: Impossibile recuperare bzip2:/var/lib/apt/lists/partial/it.archive.ubuntu.com_ubuntu_dists_trusty-updates_main_source_Sources Somma hash non corrispondente
I tried the following solutions
sudo rm -r /var/lib/apt/lists/* -vf
sudo apt-get update
sudo apt-get autoremove
sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade
see note
On some computers worked fine but not for all.
For other computers I had to install the new version from dvd
