Unbound variable?

i don’t know what this means and i don’t know what i’m doing, so i’m going to need this explained like i just walked out of Ben Franklin’s Liden Jar lab and i’ve never turned on a computer before.

i installed desktop raspbian (couldn’t figure out the regular debian setup) on an HP prodesk and ran the curl install command. i can’t even post the full output script because “new users are not allowed to post more than 2 links” on this forum. so anyways, here’s the tail end of the output:

0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded.
% Total % Received % Xferd Average Speed Time Time Time Current

100 9 100 9 0 0 37 0 --:–:-- --:–:-- --:–:-- 37
main: line 140: yq_sha256[$system_arch]: unbound variable

i don’t know what this means. does this mean it worked? i can’t find an umbrel host using angryIP from my windows machine.

any clarification or advice would be appreciated.
