Is AGPL-3.0 compatible with GPL-2.0-or-later?
It depends — here's on what:
GPLv3 family combines with AGPLv3; GPLv2-only does not. See overrides. Result license is the more restrictive of the inputs. You must satisfy every input license's notice and source-offer terms. Verify pairwise compatibility first.
Resulting work's license: AGPL-3.0-only
