[SOLVED] Sudo is unable to resolve host name

linuxuser7 · 05-14-2018, 04:40 PM

I installed Linux Mint where I gave the computer a name that I later became unhappy with so I went into Settings ---> Details and changed the name of my computer. Now whenever I do

Code:

sudo apt install program_name

I get a message

Code:

sudo: unable to resolve host computer_name

It does let me enter my password and does work, but how can I get sudo to resolve my computer name?

I'd suggest you look at the Ubuntu page below as I expect it will be the same with Mint. Make sure you have the correct name in both files mentioned.

Just as an aside, you don't actually need to prefix the apt command with sudo.

apt install program_name should work fine.
