Bug Description
Mint Update Manager error (toolbar: view --> information) in Mint 18 (Cinnamon x86; Kernel: x86_64 Linux 4.4.0-31-generic):
++ Starting refresh (including refreshing the APT cache)
-- Exception occured [*sic*] in the refresh thread: <class 'subprocess.
And Update Manager shows a red cross.
The problem is intermittent.
Updates do appear in the Manager and install without problems. Also, 'apt-get update 'and 'apt-get upgrade' work fine.

I am also experiencing this issue on Linux Mint 18 (Cinnamon AMD64, Kernel: x86_64 Linux 4.4.0-21-generic).
The problem seems to be consistent. The initial refresh after system boot seems to complete without issue. However, subsequent auto-refresh attempts fail, yielding the red X, and leaving the following in the log (note that I have shortened my refresh interval to five minutes for troubleshooting purposes):
07.19@14:58 ++ Launching mintUpdate CalledProcessEr ror'>
07.19@14:58 ++ Initial refresh will happen in 10 minutes, 0 hours and 0 days
07.19@14:58 ++ Starting refresh
07.19@14:58 ++ System is up to date
07.19@14:58 ++ Refresh finished
07.19@15:08 ++ MintUpdate is in tray mode, performing initial refresh
07.19@15:08 ++ Auto-refresh will happen in 5 minutes, 0 hours and 0 days
07.19@15:08 ++ Starting refresh (including refreshing the APT cache)
07.19@15:08 -- Exception occured in the refresh thread: <class 'subprocess.
As stated above, manually clicking the refresh button seems to work, as does apt-get update.
In the course of troubleshooting this, I think I may have stumbled upon a work-around. Grasping at straws, I tried disabling IPv6 with NetworkManager. This seemed to resolve the issue. I re-enabled IPv6, and the issue re-appeared once more. From this I referenced the IPv6 configuration of other machines on my network running Mint 17.2 and 17.3 (none of which are having issues of this sort). On the problem computer IPv6 was enabled, but the drop-down box in the "Addresses" field was blank. I changed this to "Automatic" and the auto-refresh cycles have completed for the last several hours without issue.
I will leave this configuration running and update with any changes. I hope this helps.
