True, we know the OP has a problem with with sudo. What we do not know is the hostname he chose during the installation, although it looks like it was "localhost" from the second line of 127.0.0.1 localhost 127.0.1.1 localhost The installer recommends a single word for the hostname. The "single" aspect is the result of a number of years of experience and bug reports. Although "localhost.localdomain" is not an invalid hostname the OP does not appear to have used it. (We have not been given the contents of his /etc/hostname explicitly). What was the problem with his resolv.conf? Have I missed that? -- Brian.
