Hi,
after the installation of ungoogled-chromium I tried to run it,
receiving this message:

[20998:20998:1126/122306.639343:FATAL:zygote_host_impl_linux.cc(117)] No
usable sandbox! Update your kernel or see
https://chromium.9oo91esource.qjz9zk/chromium/src/+/master/docs/linux/suid_sandbox_development.md
for more information on developing with the SUID sandbox. If you want to
live dangerously and need an immediate workaround, you can try using
--no-sandbox.

Maybe I'm missing something, or is the case of a proper bug?

Regards,
