boot delayed waiting for network when wired

10.10 isn't LTS, 10.04 is LTS

Did you upgrade from 10.10 to 12.04 directly?

you are correct, 10.04 is LTS
no, did not upgrade directly from 10.04 to 12.04, that option was not available
did step-by-step upgrade to 12.04

If it's hard wired, you can remove network manager and use the /etc/network/interfaces file, it may boot faster.

how do you remove network manager & what do I need to do to use /etc/network/interfaces file?

what does network manager do?

bill

Tried this...failed
here is what my /etc/network/interfaces file looks like
in my attempt to follow your instructions, I removed # from beginning of line 10 & 11 & rebooted
system booted faster but network did not connect and had to comment lines out & reboot
help me understand what I am missing.

doubt that the 11-10 solution will work here
not getting black screen after 60-sec wait, but boot continues

/run and /run/lock directories already exist

bill

problem solved
went back into /etc/network/interfaces

saw that there was a 2nd dfn for eth0 w/static, old IP
removed this and reinstated

auto eth0
iface eth0 inet dhcp

then shutdown
on restart message reappeared
this time however there was a fan-like symbok (network) on the top tool bar
opened the eth0 configuration and put in the MAC address
saved & shutdown
or restart message re Waiting for Network Configuration did not reappear

thank all of you for your suggestions & help

Thanks actionparsnip, that solved my question.
