Burp Won’t Update

This is related to problems starting Burp’s browser on Ubuntu Pro running on ARM

I’ve repeatedly had problems with Burp not updating. I don’t use autoupdate. When Burp starts it tells me there’s an update.

I first make backup of my entire system (an Amazon Machine Image or AMI) and then I update.

But the update either fails or it looks like it ran but my system is still using the old version — 5.4 in this case.

So what I did was try to manually run the update by double clicking the file. That still didn’t work.

I fixed it by running the update file from the command line and got a better error message which said that burp’s browser couldn’t be configured.

Why?
Because in order to try to fix a problem with burp’s browser in the past, I had corrected a file permissions issue according to Portswigger’s instructions (in a separate post) to set the chrome sandbox directory in the burpbrowser folder to mode 4755 and make the owner root. That made it impossible for the update process to install burp with my current user.

What I did was delete the directory for the burp browser in my Burp installation.
