Re: Channel details of profile generation

[Phil <phil@beadling.co.uk>]

Hi Simon,

I'll specifically elaborate on the guix pull error in this e-mail, I
follow-up on other items later (apologies my first e-mail as perhaps too
busy!).

Yes - the issue here appears to be the inclusion of a package from a
private channel in the manifest.

If I create a manifest only using Guix packages - everything looks OK - eg:

ubuntu@test-image:~/guix-manifests$ cat test-manifest.scm 
(packages->manifest
 (list (specification->package "python@3.8.2")))
    

ubuntu@test-image:~/guix-manifests$ guix package -m test-manifest.scm -p ~/guix-profiles/test-profile
The following package will be installed:
   python 3.8.2

The following derivation will be built:
   /gnu/store/yd7093md8q5xa1s3zn3nwmh9qcpnwpjr-profile.drv

building CA certificate bundle...
building fonts directory...
building directory of Info manuals...

building profile with 1 package...
hint: Consider setting the necessary environment variables by running:

     GUIX_PROFILE="/home/ubuntu/guix-profiles/test-profile"
     . "$GUIX_PROFILE/etc/profile"

Alternately, see `guix package --search-paths -p "/home/ubuntu/guix-profiles/test-profile"'.

ubuntu@test-image:~/guix-manifests$ GUIX_PROFILE="/home/ubuntu/guix-profiles/test-profile"
ubuntu@test-image:~/guix-manifests$ . "$GUIX_PROFILE/etc/profile"

ubuntu@test-image:~/guix-manifests$ guix pull -p ~/guix-profiles/test-profile -l
\Generation 1   Jan 04 2021 17:00:58\   (current)
  python 3.8.2
ubuntu@test-image:~/guix-manifests$


But if I now also add a package from my private channel to the manifest:


ubuntu@test-image:~/guix-manifests$ cat test-manifest-2.scm 
(packages->manifest
 (list (specification->package "python@3.8.2")
       (@ (py-test-pkg) py-test-pkg-develop)))



ubuntu@test-image:~/guix-manifests$ guix package -m test-manifest-2.scm -p ~/guix-profiles/test-profile
The following packages will be installed:
   py-test-pkg 4.72-0.2aa0874
   python       3.8.2

It installs OK but the same guix pull comamnd now fails:


ubuntu@test-image:~/guix-manifests$ guix pull -p ~/guix-profiles/test-profile -l
\Generation 1   Jan 04 2021 17:00:58\

Despite this the test package did install correctly (py-test-pkg
installs module example_project):

ubuntu@test-image:~/guix-manifests$ which python3
/home/ubuntu/guix-profiles/test-profile/bin/python3
ubuntu@test-image:~/guix-manifests$ python3 -m example_project --myparam testing
The parameter was: testing
