I am new in Linux and I am trying to install Ubuntu 12. 04 on my pc. After downloading and "burning" it on USB I try to install it. But there seems to be an error on the installation. "Could not retrieve the required installation files". It also tells me to check another file. This file writes something like this:
ERROR CommonBackend: The md5 of the metalink does match ERROR CommonBackend: Cannot authenticate the metalink file, it might be corrupt
After that there is also another error which says:
ERROR CommonBackend: Invalid md5 for ISO C:\ubuntu\install\installation.iso (14ad92270218a8925d802b3d3b6e140f != 6c086700fd56a27a09b5de552ae054fd)
Any here? What seems to be the problem?
