Hello Carl,

Carl Dong <contact <at> carldong.me> skribis:

This one appears to work for me (I interrupted it before it was done
compiling all the toolchains, though.)

When I put b6dc08393e6a8313b88ce422fc3c1e4e9c0efc6f in .guix-channel and
use that as my channel, it also works fine (well, I commented out the
toolchains as well.)

That definitely looks like a bug.

Could you send the faulty info-dir.drv file?

Thanks,
Ludo’.
