assertion failed when using computed versions #3716
Description
I'm trying to use computed versions in opam 2.0.2 to make multi-repository packages easier, but it leads to an assertion failure in opam:
+opam install depext
Fatal error:
File "src/solver/opamSolver.ml", line 231, characters 18-24: Assertion failed
'unset TESTS; OPAMYES=1 export OPAMYES; set -uex; opam install depext' exited 99. Terminating with 99
