Any time I try to install software or updates, I get the following message (or a slight variation):
dpkg: error:
parsing file '/var/lib/dpkg/available'
near line 10650 package 'libreoffige-writev':
field name `Replaces>' must be followed by colon
I have no idea what it means, but it always insists that `Replaces>' be followed by a colon.
