The author is asking how to change hostname when it includes the appendage ´default-string´,

If root is required to change the file in the path etc/hosts should this be changed? This is my configuration.

127.0.0.1       localhost
127.0.1.1       myhostname-Default-string

The following lines are desirable for IPv6 capable hosts


::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

As my question asks, why am I seeing ´default-string´?

Also, is this standard formatting for hostname in the directory mentioned above?

This answer appears to say this is not the case.

Therefore, is it safe to use root to change?

By the way. I have not changed my hostname, ever.

  • Maybe it's because you didn't enter a hostname during installation - just a guess. But yes, you can easily change your hostname here and in the file etc/hostname. – Artur Meinild Feb 16 '21 at 14:31
  • Thanks. That makes sense now. I didn´t enter one during installation, As far as I remember. I get ´sudo: unable to resolve host *****: Temporary failure in name resolution¨ when running sudo apt update, for example. But then on entering password commands seem to work okay. – XJMZX Feb 16 '21 at 14:59
