Upgrade from Kubuntu 7.10 to 8.04 removes hostname from /etc/hosts

[Glenn Ramsey]

A vary bad consequence of this is that it causes sudo to fail locking the administrator out of the machine.

Prior to the upgrade I had manually edited /etc/hosts, maybe the installer doesn't like that?.

To fix it you have to boot in failsafe mode and manually add the hostname to /etc/hosts.

e.g.

127.0.1.1 myhostname

This bug was marked as a duplicate, but that appears to be incorrect. This is a report that the upgrade *broke* the /etc/hosts file, which is a bug in itself, separate from sudo's behavior when the hostname is not resolvable.

Thank you for taking the time to report this bug. Can you add the files in /var/log/dist-upgrade/ ?

[Glenn Ramsey (glennr)]

apt.log is empty

I think what I had done to to the /etc/hosts was to remove the '127.0.1.1 myhostname' entry and change it to '192.168.1.2 myhostname' since I had a static IP configured. After the upgrade I would have expected that to be left alone.

These log files only cover 2008-01-01 which I don't imagine was the day that this happened. Do you have any other log files in '/var/log/dist-upgrade/' ?

[Glenn Ramsey (glennr)]

No that's all that is in there:

ls -l /var/log/dist-upgrade/
total 24
-rw-r--r-- 1 root root 0 2008-01-01 11:06 apt.log
-rw-r--r-- 1 root root 18207 2008-01-01 12:38 main.log
-rw-r--r-- 1 root root 1375 2008-01-01 11:59 main_pre_req.log

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.

[Glenn Ramsey (glennr)]

Hi this isn't an issue any more since I only needed to upgrade once. Haven't upgraded since and will be sticking with 8.04 for a while, but I will try to remember to look out for this next time I upgrade.

removing gutsy2hardy tag. not closing since it's not clear if later releases are affected. Having a test case would help determine if we do indeed have a bug at our hands.
