I have solved the issue myself in Precise pongolin (ubuntu 12.04 based linux mint 13 maya ) after trying a user comment posted in the above-mentioned fabrizio post.

I think many standalone configuration files are being migrated to directories in ubuntu.

That resolve.conf is one such victim file. It is not found in /etc/resolve.conf.

instead /etc/resolve.conf/resolve.conf.d directory is there.

All we have to do is edit the line 355- from /usr/lib/uck/ to as below:


 if [ ! -e "$REMASTER_DIR/etc/resolv.conf" ] ; then
  echo "Copying resolv.conf..."
  cp -f /etc/resolvconf/resolv.conf.d/* "$REMASTER_DIR/etc/resolvconf/resolv.conf.d/" ||
   failure "Failed to copy resolv.conf, error=$?"


now the script instead of blindly trying to copy a non-existant resolve.conf, successfully copies the whole directory to its destination.

Now there is no more error.

Pls tell me how to submit as a patch to uck.

With love from India.

The resolv.conf error can be fixed by simply editing the remaster script to show lines a) line 355-58 from /usr/lib/uck/

instead of cp resolv.conf….
replace resolv.conf with /etc/resolvconf/resolv.conf.d/original /etc/resolvconf/resolv.conf.d/

By editing as such i was able to have net access during build.

Thanks, the above workaround resolved for me as well.
