When I download the Ubuntu Touch SDK, I receive the following erros:
W: Failed to fetch bzip2:/var/lib/apt/lists/partial/us.archive.ubuntu.com_ubuntu_dists_saucy_universe_binary-amd64_Packages Hash Sum mismatch
W: Failed to fetch bzip2:/var/lib/apt/lists/partial/us.archive.ubuntu.com_ubuntu_dists_saucy_universe_binary-i386_Packages Hash Sum mismatch
Can someone tell me how to solve the problem?
