** Description changed:
Using chromium browser on ubuntu bionic (the apt version), the wrong
user agent is present in chromium 111 and 112. When testing the arm64
build, the user agent should contain the string aarch64 however it
contains the string x86_64. Many websites use the user agent to provide
download links for the correct architecture that the system is running
and this incorrect user agent will interfere with that process. I am not
aware if i386 and armhf builds are also affected by this or not. This
was not an issue in chromium 110 builds, they had the correct user
agent.
There is YouTube bug to go alongside this as well. In chromium 110+, YouTube
is blocking higher than 480p content on Linux unless the user agent is x86_64.
Here is the YouTube debug info from chromium 110 (using the default user agent
which correctly has aarch64).

YouTube is reporting back that this is some random branded TV. Changing
the user agent to x86_64 is a hack that allows for higher resolutions to
be played back and the output from debug info is "normal" again.
- I would like for this to be corrected at YouTube as well as in chromium-
- browser debs.
+ If you have contacts at Google that would be great if the second issue
+ could be fixed at YouTube.

chromium 111 and 112 have the wrong architecture in the user agent
Status in chromium-browser package in Ubuntu:

Bug description:
Using chromium browser on ubuntu bionic (the apt version), the wrong
user agent is present in chromium 111 and 112. When testing the arm64
build, the user agent is expected to contain the string aarch64
however it contains the string x86_64. I am not aware if i386 and
armhf builds are also affected by this or not. This was not an issue
in chromium 110 builds, they had the correct user agent. I am assuming
this is likely an issue with chromium source and not packaging in
particular.
On the other hand, using x86_64 fixes a bug that youtube has on
aarch64 user agent, where it thinks it's a Hisense TV and limits max
resolution to 480p since chromium 110+. playback debug info from
youtube to show that:
