I cannot confirm this on the same git version and platform: # passed all 174 test(s) 1..174 Christian's suggestion from your other thread about running the test with the options -i -v -x should also help here to give more detailed error messages: https://lore.kernel.org/git/CAP8UFD30et-kL8dFoWvh7aPf4AKbzGxSzTuA=B3YNHZL_1axFA@xxxxxxxxxxxxxx/ > *** t9001-send-email.sh *** > ok 1 - prepare reference tree > ok 2 - Setup helper tool > ok 3 - Extract patches > not ok 4 - No confirm with --suppress-cc Since the tests 1-3 do not call git send-email, but test 4 and most of the following do, I suspect the system is missing some dependency packages needed for git send-email, probably mail-related Perl modules. Installing Fedora's git-email package is probably enough to fix this: dnf install git-email Stefan
