you can not change maps that are in the PERMANENT mapset.

make a local copy first,

g.copy vect=roads,roads_local

and check if a DB connection exists for the map:

G61 > v.db.connect -p roads
Vector map <roads> is connected by:
layer <1> table <roads> in database </home/hamish/grassdata/spearfish60/PERMANENT/dbf/> through driver <dbf> with key <cat>
