do-release-upgrade -d terminates

[ovl666]

Upgrading from Ubuntu 18.04.4 LTS to Ubuntu 20.04 LTS stops.
I removed all PPAs, check and removed all hold and partial installed packeages with:

dpkg -P $(dpkg -l | grep "^rc" | awk -F" " '{ printf $2 " " }'|sed -e 's/\:.* / /g')

but still not possible to upgrade.

Thanks

Oliver
