Errors with make test

Hi, when I run make test some of the tests are failing because of an issue with the PGP key, and if I comment that out I get a different error, for another test.
Any idea why this is happening?

The Go version I use is go version go1.15.5 darwin/amd64

$ make test

When I configure to skip that test (with t.Skip), I get a different error in another test:

make: *** [test] Error 2

Start by reproducing make test with the Go version and environment details provided. Inspect keysource_test.go:49 and stores/ini/store.go:292, then review test.sh and the PGP test-key setup. Done means the reported test failures are explained and the full test command completes without skipping tests.
