I keep getting:
Warning: "keytool" is not available, so the CA can't be automatically installed in Java's trust store! ⚠️
When it plainly is available, I can just type "keytool" and it works. JAVA_HOME is set just fine. I'm really at a loss because everything else can access it just fine.
Weird! Can you give us the output of
which keytool and
echo $PATH? Are you running mkcert with sudo, maybe?
