[L2Ork-dev] Problems installing on Ubuntu Studio 20.04

[Albert Graef]

Hi Rukshan,

Thanks for pointing that out. Probably there are alternative providers for
that package. Many people prefer jack2 over jack1, so Ubuntu, like many
other systems, has packages for both. That's an endless source of
confusion. Ah, the wonders of Linux land. ;-)

Anyway, in the OBS xUbuntu_20.04 buildlogs I can see that libjack0 gets
pulled in there as well, so that's probably the right package to add to
that list.

BTW, pro tip: Never post screenshots of text from a terminal, always just
post the text itself, that's much more useful. Thanks. :)

Albert
