I use FreeBSD 10.4/amd64 and execute portdowngrade inside a jail. When I try to downgrade a port to a previous version I see this error message
portdowngrade security/tor r449591
svn: E170013: Unable to connect to a repository at URL 'http://svn.freebsd.org/ports/head/security/tor'
svn: E000043: Error running context: Protocol not supported
Something went wrong with svn... Ensure you have the correct revision!
The revision is correct. I was able to workaround this issue by modifying /usr/local/sbin/portdowngrade and changing the line
Thanks. I've used https as that's the recommended protocol.
