kd4e Chromium is OS sensitive?
I thought Chromium was essentially self-contained.
Unfortunately, many things have the ability to break other things. After a problem has been solved it may seem obvious in retrospect that what went wrong could have gone wrong.
kd4e Why would it be able to do 'Unlock bootloader' (communicate with the phone) but not 'Download release' (communicate with the Internet)?
'Download release' would seem a generic browser activity.
I just tried and no problem downloading a .wav file from the Internet.
What the installer does is not the same thing as when the browser downloads a file to store in the file system for you to use later. It is fetching the contents across the Internet, storing it in a special temporary file, and then sending the contents of the file over WebUSB.

Maybe the problem is insufficient temporary space, which is something various Linux distributions configure differently.
