Builds OK on Debian testing running on core i5 + 8 GB RAM ; fails two doctests :

----------------------------------------------------------------------
sage -t --long --warn-long 46.0 src/sage/groups/perm_gps/permgroup_named.py  # 3 doctests failed
sage -t --long --warn-long 46.0 src/sage/interfaces/r.py  # 3 doctests failed
----------------------------------------------------------------------

The second one is with us since the update to R ( see this report, discussed on the relevant tickets but no solution choosen yet).

The second one is new and is related to newly-obtainble permutation groups results (which used to fail but now return (seemingly sensible) results) : see attached file...

HTH,

The R issue should actually be fixed, the ticket you linked just needs review.

regarding GAP tests, they are fixed in #26856
