Okay, I am slowly moving forward: I had not installed openssh-server...

This indicates that the patches to Sage did not apply successfully. Can
you check those? The patches in SAGE_ROOT/devel/sage/.hg/patches/
should exactly with the patches here:
https://github.com/sagemath/sagecell/blob/master/sage-patches/01-sage-embedded.patch
https://github.com/sagemath/sagecell/blob/master/sage-patches/02-sage-show.patch
In particular, my guess is that the second patch is not applied. If it
isn't applied, you can apply it manually by going to
SAGE_ROOT/devel/sage/ and doing:
hg qimport -P
https://github.com/sagemath/sagecell/raw/master/sage-patches/02-sage-show.patch
Then do 'sage -br' to make sure that Sage builds the new code and can
start up.
Thanks,
Jason
