Even faced an issue with running the BNSupport tool and got the following error;
|\Error copying file from packed archive /opt/bitnami/bnsupport/bnsupport-0.7.6-linux-x64.
run to /opt/bitnami/bnsupport-regex.ini
:Destination not writable
Abort, Retry, Ignore ? [A/r/i]i
Retrying didn't work. So I ignored it.
Error changing permissions to 00644 in /opt/bitnami/bnsupport-regex.ini
I probed around using FTP to check if I could change the permissions but was not able to find the file.
