11002  2024-01-29 21:36:32 pip install streamlink
11005  2024-01-29 21:37:41 pip uninstall streamlink
11008  2024-01-29 21:38:26 sudo apt install streamlink
11009  2024-01-29 21:40:46 sudo apt show streamlink
11015  2024-01-29 21:50:11 sudo apt remove --purge streamlink
11017  2024-01-29 21:50:43 sudo apt install streamlink
11018  2024-01-29 21:51:52 pip uninstall streamlink
11019  2024-01-29 21:52:10 pip install streamlink --ignore-installed <==THIS!

A number of these commands *failed* due to some inconsistencies in my system.
But after doing my best to remove streamlink the final command succeeded and it
now shows the correct version:

$ streamlink -V
streamlink 6.5.1

I don't know what that statement means...
What is "outside a virtualenv"???

I run my Ubuntu Server on a dedicated Lenovo minitower as one of several
multi-booted systems. But that is hardly called virtualenv, right?

And after initial install I have only seldom started any other of the operating
systems than the server.

There are an Ubuntu 20 desktop and a Windows 10 which came with the PC and is
left there because it is probably the only way to upgrade the system firmware
with Windows.

Plus there is a mini-system running GParted standalone which is (infrequently)
used to image the server partition to a USB drive for backup.
