I have tested 20c08a in my reverts, it is neither the bad commit nor
does it fix it.

Yes.

It still gets stuck (sometimes with enlightenment, one time with
udisks, restarting the install fixed it once).  After getting stuck,
this different error message is shown now; no TLS error (copied by
manual typing, there may be typos):

Nope, this always works without issue.  Ricardo had written about TLS
errors with 0ad some two or three days ago, but I do not get errors
with 0ad.  The issue is present when installing Enlightenment DE from
the installer on both my Macbook and my Beebox every time, but not
when installing to a VM (but maybe it was just luck)
