I attempted to upgrade my ubuntu-dapper using the 4.0.2 Ubuntu tar ball. The install failed with " libgmp3...MISSING" error.
For my current zimbra install, I had used the GA release of debian and used the Ubuntu patch from the wiki to get past the libgmp3 problem. The patch contained:
The patch code from the wiki has:
- PREREQ_PACKAGES="sudo libidn11 curl fetchmail libgmp3 libxml2 libstdc++6 openssl"
+ PREREQ_PACKAGES="sudo libidn11 curl fetchmail libgmp3c2 libgmp3-dev libxml2 libstdc++6 openssl"
Perhaps the package requirements have not been updated on the Ubuntu release?
