hostname disappear from /etc/hosts

In debian, after installed tinycp, I receive the following error when run any sudo operation

sudo: unable to resolve host mymachinehostname: Name or service not know

I checked the hosts file and the hostname disapperead from here. If I insert hostname manually, it will be deleted after reboot.

Hi.

We have rebuilt hostname and /etc/hosts generator.

Now should be ok.

I am having this issue right now. Exact same.

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

Host file is stripped down to this after TinyCP install:

127.0.0.1 localhost.localdomain localhost
::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

I added the hostname entry back in just below the local host entry, and after reboot, gone again. This makes TinyCP unusable.

I have now verified this was the case. I updated the /etc/hosts file 3 times, rebooting after each, to find it had removed my host entry each time. I then updated the host file one last time and uninstalled TinyCP via:

apt-get purge tinycp

followed by:

apt-get autoremove

to clean up the rest of the package files. I then rebooted and checked the /etc/hosts file and it is now intact.
