guix pull: = error: You found a bug: the program '/gnu/store/d9dc5jdlhbp4zdx1m9ffr3fmhyg= 60zy8-compute-guix-derivation'

Please report it by email = to <bug-guix@gnu.org>.

However, I remember that the package guile-git was not a d= ependency at the time of v0.12 but it is now. So, rather than reporti= ng the bug I have tried to install guile-git:

$ gu= ix package -i guile-git

<= br>

This has been reported before [2]. The workaround sugge= sted there was to download the source directly. However, this now fai= ls too:

$ guix download https://mirror.hydra.gnu.org/file/libgit2-= 0.25.1.tar.gz/sha256/1cdwcw38frc1wf28x5ppddazv9hywc718j92f3xa3ybzzycyds3s

ERROR: Throw to key `gnutls-error' with args `(#<gnutls-err= or-enum Error while reading file.> set-certificate-credentials-x509-trus= t-file!)'

I think the error message is a little mi= sleading here. I have tried to download the same file from a more rec= ent guix installation on another system which also fails. Essentially= , the error is 'file not found'.

So, the situation= is that neither a substitute nor the source code are available for libgit2= and Guix gets stuck. How should one resolve cases such as this?

Best regards,

Paul.
