Amongst other things, I am trying to change my hostname with a script. Basically the script
seds the values of
I tried this on Ubuntu 16.04.4 in the past and worked well.
Now, on 16.04.6 (or just by chance), I am getting errors with the same script. Just as I change the
hostname, the change on the
hosts files takes a long time (probably because
sudo is trying to reach the new host which has not yet placed in the
hosts file but I did not know
sudo uses such information) and I get an error:
sudo: unable to resolve host xxxx
sudo: unable to resolve host ubuntu. Following script commands have the same problems or fail.
But obviously it is not possible to change at once the values of both files
Why did this happen? Is it something new in that Linux distribution version? I read other people having the same problem but never happened to me before, I was always able to edit both files with sudo with no other inconveniences.
