any suggestions how escape / tackle this?
update:
i've managed upgrade python using make install instructions found here, however, python error upon do-release-upgrade identical.
the official upgrade notes manual said releases states:
to avoid damaging running system, upgrading should done 1 release next release (e.g. ubuntu 12.04 ubuntu 12.10) or 1 lts release next (e.g. ubuntu 10.04 lts ubuntu 12.04 lts) if wish 'skip' version, can data , fresh installation, or progressively upgrade each successive version.
