Hi!

Thanks for reporting this.

What usually (though, mercifully, rarely) happens is that the hash 
is correct at the time of packaging, then upstream goes and moves 
a perfectly good git tag instead of making a new one, and the hash 
becomes wrong in retrospect.

This case was different: the original packager correctly ran ‘guix 
hash -rx .’ on their clone of the barrier git repository, but did 
not first check out the submodules and was unaware that these 
affect the hash.  I don't think the original package ever built, 
or at least fail to see how it could have.

Fixed on master[0].

Closing, but could you guix pull & confirm that it works for you?

Kind regards,

T G-R

Hey there!

Am trying to install barrier on my computer and guix tells me 
there is a
hash mismatch. I’m able to install other applications, and I think 
this
is a case where the hash in the package description might be 
wrong?

More than happy to provide more info, please let me know how i can 
help
debug this.

Cheers,
Vishakh Kumar
