sorry I cannot. I only build Sage releases on my laptop (this takes ages and I have to make sure it does not heat too much).

after trying comment 18 in #26686, I can build Sage with make sagenb, but make -j1 still does not want to build the documentation:

$ make -j1

Does make doc-clean fix that latter error?

yes it does. Thank you. But it was the first time since years that building Sage from source does not work.

So is there anybody that can actually reproduce the problem from #26686? If not, this should be closed as "worksforme".

I will try to rebuild Sage 8.6 from scratch, to see if the problem is reproducible.

By the way, while creating this ticket, you should have copied the description of the problem I had, since the description of this ticket is not very informative...

I tried again building Sage 8.6 from scratch and it worked fine. Since I'm unable to reproduce the problem, we can close that ticket.
