sudo: unable to resolve host Cloudron: Name or service not known

[Ritesh]

Hi,

I wanted to remove the manual backups. I logged into the server using SSH using my server's login details and tried to remove the backup files following this: https://docs.cloudron.io/backups/#cleanup-backups

rm -rf showed Permission denied, then I used sudo and then it said this:

sudo: unable to resolve host Cloudron: Name or service not known

I ran sudo nano /etc/hosts which showed this:

127.0.0.1 localhost

# 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
ff02::3 ip6-allhosts

Should I make changes to this file? Or does Cloudron create separate SSH credentials?

Please guide me.

Thanks

This is because the hostname Cloudron is not in /etc/hosts . You can change the hostname to something meaningful (to you) and add an entry in /etc/hosts as well. That way the warning will go away.

For example, add something like below :

127.0.1.1	myservername
