How can I install Jami Beta on FreeBSD in Ubuntu 20.04 chroot?

Ok, that makes sense, so let me recap it.

I have installed

root@alef14:/# apt show libwebpmux3/focal
Package: libwebpmux3
Version: 0.6.1-2

as you said, while I should have something more like

libwebpmux-3-0.6.1-2ubuntu0.20.04.1

Plus, again as you said, I use a different architecture (which I wasn’t aware before), this is

root@alef14:/# lscpu
Architecture:        x86_64
CPU op-mode(s):      32-bit, 64-bit
Byte Order:          Little Endian

instead of

amd64

It’s because I run Ubuntu as Linux Compatibility Layer on FreeBSD, see

  1. https://wiki.freebsd.org/Linuxulator
  2. https://github.com/mrclksr/linux-browser-installer

This apparently makes difference.

I didn’t mention that earlier, because you can install Brave/Vivaldi browser or LBRY-Desktop app. as it’s regular Ubuntu (which I did).

The most important thing is we found the reason (thanks to @Firenze @bandali ).

I’ll update the title to reflect all the findings.

Thanks again!

UPDATE:
I can’t update the thread title. :frowning:
