MINOR upgrade error

Everything seems to be working fine but as I got the ‘report it to the forum’ message …
During install it froze at downloading ~10Mb of 21 or so for a good while before it timed out with the above message

-f dist-update
tells me I’m not missing anything
Just seems weird.

Sounds like a problem connecting to the server - were you using Ethernet or Wifi ? Checking for updates again manually should finish the upgrade if it was just a temporary network problem.

Agreed, ethernet.
But doing a manual update or forcing dist-update indicates I have everything just seems a bit odd.

Upload your apt logs and they should show the cause of the error.
