Comment 27 for bug 1007293

never ending story:

To #25:

I configerd dns server in /etc/network/interfaces by adding the following lines manually:

dns-nameservers server1 server2 server3
dns-search domain.name

nothing else! I left resolv.conf untouched.
This Bug is the reason, why I postponed the upgrade of my machines until Ubuntu upgrade will work in a more or less proper way. I testet it on three of my machines, and all shows the same behavior. If I reinstall network-manager (instead of useing ifupdown) to avoid network response delays, the following happens to all machines:

1. After reboot: bootmessage says:" * starting cups printing/server"

2. Perhaps 20 seconds nothing happens

3. After that bootmessage says: "Waiting for network configuration ...."

4. Perhaps 30 seconds nothing happens

5. After that bootmessage says: "Waiting up to 60 more seconds for network configuration ..."

6. Perhaps 60 seconds nothing happens

7. After that bootmessage says: "Booting system without full network configuration"

8. System boots up to login manager

But network is still not configured, one has to restart network-manager manually to get the system working.

In summary: If I install a Ubuntu 12.04 system from scratch, I can have a working system, but I have to use network-manager and IP numbers in yp.conf instead of machine names. If I want to upgrade a Ubuntu 10.04LTS system, I get a lot of trouble.
