I'm sure I'm missing something, but the 1.8.0 or 1.8 channels look very much valid to me, and also according to juliaup list itself:

% juliaup list | grep -e '1.8.0[^+.~-]'   
 1.8.0            1.8.0+0.x64       
% juliaup list | grep -e '1.8[^+.~-]'  
 1.8              1.8.1+0.x64

The channel is valid, but it is not installed. juliaup status lists all installed channels. juliaup list lists all channels, installed or no.

The error message could probably use some clarification.

I think this is related to #115

I'm assuming that @MatthijsBlom explanation is correct, if not, please reopen.

Yes, that is https://github.com/JuliaLang/juliaup/issues/115.
