--- Comment #2 from Sönke Ludwig <[email protected]> --- Upon further inspection, this is caused by a bug in DUB 0.9.23 that has already been fixed on master: https://github.com/D-Programming-Language/dub/issues/564 The root cause is in a dependency that transiently in turn had unresolvable dependencies. This caused the upgrade suggestion check to error out. Both the error and the bad error message will be fixed for DUB 0.9.24. I didn't realize that it breaks the website build in such a bad way. The workaround is to first run "dub upgrade --missing-only" and only then build with "--nodeps" (I guess Martin added the --nodeps as a quick fix?). I'll also prepare a new DUB release including the fix ASAP. --
