bug#41715: The program '/gnu/store/foobar/compute-guix-derivation' failed to compute the derivation for guix

[o.rojon@posteo.net]

Hi Ludo,

guix pull --roll-back did not solve the issue. The only thing I believe 
to have changed is the "host version" portion of the error message.

'which guix' actually points to ~/.configu/guix/current/bin/guix. Should 
this command yield a different value?

I have actually not done anything regarding either guix-daemon or 
offloading. The only things I did after the fresh install were a 
reconfigure and passing a manifest file to 'guix package -m'.

I may have misunderstood what Jakub wrote because I am unsure what a 
transient failure is. The portion I believe to have understood 
essentially says "try again later and it should work".

I found the logs of 'compute-guix-derivation', but I was unable to see 
anything meaningful opening the .drv.bz2 file in emacs. Am I doing 
something wrong?

I wont be on my guix machine for some days now but appreciate pointers. 
:)

Olivier
