[ubuntu] just upgraded - admin applications won't start

[kstella]

I upgraded to Hardy only yesterday. When I started up again, I saw that there were updates waiting. There were also other things I wanted to do: install programs, change settings, etc.

Every time I try to do those things, I see the little button/bar at the bottom that says "Starting Administrative Application." But nothing ever comes afterward. No window, nothing. Any ideas?

Post the outputs of:-

hostname

and

cat /etc/hosts

[kstella]

stella

and

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 192.168.0.10 stella.CERSA

I'm not using that IP anymore, though, so now I also wonder why that came out.

First boot Ubuntu in Recovery Mode, then backup the hosts file with:-

cp /etc/hosts /etc/hosts.bak

and after that's done, open the hosts file for editing with:-

nano /etc/hosts

and edit it to look like this:-

127.0.0.1 localhost
127.0.1.1 stella

# 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

Then save the file and see if the problems are now solved.

Okay. Which option do I choose at the end of the recovery mode sequence? I chose "resume with normal boot" but couldn't get past the first step in the terminal; I got "permissions denied."

Also, what's nano?

Thanks.

[PmDematagoda]

Don't choose "resume with normal boot", instead press the option that allows you to be dropped to a terminal.

And nano is a command line text editor built-in to Ubuntu.

[kstella]

It didn't work. I'm sure I did everything that you said.

[PmDematagoda]

Post the outputs of:-

hostname

and

cat /etc/hosts

again.

[kstella]

stella

and

127.0.0.1 localhost
127.0.1.1 stella

# 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

The first time I read your reply, I saw that I'd forgotten to write "stella" at the end of the second line. Guess I wasn't so sure after all, sorry. So, I went back and added it.

The next time I tried starting an admin application, it was about ten minutes between entering the password and the actual appearance of the window. When the window DID appear, though, the system crashed!

But everything seems to be working fine now; no more gap between. Would you know what happened and if I should still be worried?

Thanks.

[PmDematagoda]

Does the system still crash when starting administrative applications? If not then all should be fine.
