Burp Suite Enterprise Agent - Error with Unattended Install using varfile

Azeem | Last updated: Jul 12, 2023 05:40AM UTC

I'm trying to install the Burp Suite Enterprise Scanning agent on Ubuntu. I'm getting errors when running the below: ``` $ sudo sh burpsuite_enterprise_linux_v2023_6_1.sh -q -varfile response.varfile Unpacking JRE ... Starting Installer ...

Seems there is something wrong when installing using the varfile...

Thank you for your message and for including the detailed output from the command. It looks like there may be an issue with a value in your varfile. Can you please email a copy of your varfile to support@portswigger.net so we can replicate your issue? Can you also let me know the version of Ubuntu that you are using and if you made any modifications to the varfile?
