Hi,
All of a sudden, my s3ql mountpoints have problems. They to have no
connected endpoints.
The output of log --debug all is (I removed the explicit location of my
bucket)

ValueError: No workers is not a good idea
The version of s3ql I was running was 1.16 (yes, I know it's old, but it's
a 14.04 LTS machine and I haven't had the time to do the cumbersome upgrade
path to 2.*)
I tried to use inplace versions of 1.17, 1.18 and 1.19 to see if that fixed
the problem, but they all end the same way.
fsck.s3ql correctly exist, as far as I can tell:
