The issue only happened once.

My guess is that the error has something to do with a networking failure 
or possibly a problem with running out of RAM. At some point (before 
encountering this error) I think I installed a program to automatically 
kill programs when low on memory, and I see in htop now that `earlyoom 
-r 60` is running, but I'm not sure if that's the program I installed or 
if that comes default with Trisquel. I have 8GB of RAM with somewhere 
between 4GB and 16GB of swap RAM at the time of the error.

I like the proposal in the thread you linked to ([1]).
