My Cinnamon LinuxMint shows the Update Manager with a red X in its shield indicating Error in checkAPT.py, could not refresh the list of packages.
Extract from mintUpdate log:
++ MintUpdate is in tray mode, performing auto-refresh
++ Starting refresh
++ Auto-refresh timer is going to sleep for 15 minutes, 0 hours and 0 days
-- Error in checkAPT.py, could not refresh the list of packages
How do I fix this?
When I manually run the Update Manager, the red X clears and the green checkmark appears.
However, if left alone, the red X will reappear.
