Upgrade problems 7.10 > 8.04 LTS

[Rick Knight]

Yesterday I decided to upgrade my notebkk PC to 8.04 LTS from 7.10. I 
used the "over the internet" upgrade method. The upgrade hung at 
"Setting up locales " and about 76% complete. I had to shutdown to get 
past that error and then my notebook was nearly non-functional. I was 
able the system to reboot again using some of the work-arounds mentioned 
here 
"https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/249340", 
but I still have a couple of issues...

First, when I boot to Kde desktop I have no network connection. My wired 
and wireless interfaces are up and have dhcp assigned addresses and all 
network settings look correct, but I can't access any internet sites and 
I can't ping any local network addresses. If I boot to recovery mode and 
then start KDM, everything works just fine. If I boot to Kdesktop, start 
a terminal session and then stop and restart /etc/init.d/networking 
everything is OK.

Second, SNMPD is not fully installed and I can't seem to fix it or 
configure it. When I run sudo apt-get install snmpd I get these messages...

Setting up snmpd (5.4.1~dfsg-4ubuntu4) ...
Starting network management services:/usr/sbin/snmpd: symbol lookup

dpkg: error processing snmpd (--configure):

E: Sub-process /usr/bin/dpkg returned an error code (1)

So far, everything else seems to be working, but I would really like to 
have network connectivity when I boot my PC and I need snmpd in my 
office. Can anyone offer any help solving these issues?

Thanks,
Rick
