Brother HL2360DW Error Message

[Tom Wake]

Installed Brother HL2360DW printer in Linux Lite 3.8 32 bit. I choose Brother 1200 cups as there is no 2360DW driver in list. Decided to change driver to find one that will print on both sides. Deleted printer to start over. Decided to check Synapatic package manager to see if other Brother packages exist. Got this message after I selected and tried to installed other Brother packages.

E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
E: _cache->open() failed, please report.

Please help me fix this?
