Hi, I can't open the Burp browser since I installed Ubuntu 24.04. I'm sending a screenshot Hello, I can't open the Burp browser since I installed Ubuntu 24.04. This message appears: Checking headless browser Error Aborting check due to errors. net.portswigger.browser.Zec: No dev tools websocket output from local chromium process 15331

Hi Pedro, This is due to how Ubuntu now restricts the use of unprivileged user namespaces (there is some details on this here - https://discourse.ubuntu.com/t/ubuntu-24-04-lts-noble-numbat-release-notes/39890). You can get around this by adding the following content to "/etc/apparmor.d/burpbrowser": # This profile allows everything and only exists to give the # application a name instead of having the label "unconfined" abi <abi/4.0>, include <tunables/global> profile burp-browser @{HOME}/BurpSuitePro/burpbrowser/*/chrome flags=(unconfined) { userns, # Site-specific additions and overrides. See local/README for details. include if exists <local/burpbrowser> } Then running `sudo apparmor_parser -r /etc/apparmor.d/burpbrowser` You may need to double-check that your browser path is accurate for your installation.
