I didn't explain the problem or the fix very clearly in the description.
I'm sorry about that.
If the directories have been rearranged so that my recommendation
no longer makes sense, then I would recommend that 'data' and 'pub'
should be treated the same way.
I don't have an 8.10 machine handy.
Just install the twiki package and look:
These should be symlinks
/var/lib/twiki/pub
/var/lib/twiki/data
they should point to:
/var/www/twiki/pub
/var/www/twiki/data
respectively.
