Comment 9 for bug 219653

Same issue with different selection in tasksel:

After installed minimal ubuntu server 32 12.04 I ran tasksel and select "Basic Ubuntu Server, Mythbuntu Additional Roles, Mythbuntu Frontend and Mythbuntu Master Backend" packages to install. On installation process tasksel exits with "aptitude failed (100)" error

I tried to continue to installation with "dpkg --configure -a" command and it exits with error below too:
dpkg: error: parsing file '/var/lib/dpkg/status' near line 1244 package 'makedev':
 field name `Original-Maintainer>' must be followed by colon

I edited "/var/lib/dpkg/status" package and replaced ">" with ":". After this correction I ran again "dpkg --configure -a" command. This time installation ended without any error.
