Export archive and import it on another machine

Export archive and import it on another machine

[白い熊＠相撲道]

I'm trying to export Libreoffice from one PC and import it on another one — the reason I'm doing this is that with the latest git checkout when I try to install it on a PC with a newly installed GuixSD it keeps building it from source and failing. 

Anyhow, on the machine that I have it installed I ran: 

# guix archive --generate-key
$ guix archive --export -r /gnu/store/hash...libreoffice-5.0.3.2 > libreoffice-5.0.3.2.nar 

Then copied the nar and /etc/guix/signing-key.pub to the other PC. 

There I ran: 

# guix archive --authorize < signing-key.pub
$ guix archive --import < libreoffice-5.0.3.2.nar

The last command fails with: 

guix archive: error: build failed: program `guix-authenticate' failed with exit code 1

What am I doing wrong? 

Side question — why is it building Libreoffice from source on “guix package -i libreoffice”? Recipe there, but not built on Hydra? How can I install an earlier already—built version?

Hm, I'm not sure. Are you sure the source machine's public key is in
/etc/guix/acl?

Most likely for this reason:
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=22653

You can install an earlier version by checking out a commit in the Guix
git repo from before Vigra broke, and building based on that commit [0].

When building Guix from git, be sure to pass the correct value to
./configure --localstatedir=. Most likely it is '/var'.

I think it is — I see one entry in the acl file, but since it's a hash I don't know how to confirm that it represents the much shorter hash found in the source machine's signing-key.pub file.

That's good — I can do that. I'm not really familiar with git yet — how can I determine the commit representing the point in time before Vitro broke and pull it? And how do I go back to master after rebuilding and installing libreoffice?

Thank you for reminding me of this! I would have forgotten for sure! :@)

Typically there would only be one entry in the acl file, containing
hydra.gnu.org's public key.

So, unless you do not use substitutes from hydra.gnu.org, there should
be two keys.

Also, I believe that the imported key should match the contents of
signing-key.pub. I tested this functionality while reading your message
yesterday and that was my experience. Perhaps try importing the public
key again?

I bet if you ask on #guix, somebody will know what broke Vigra and can
help you figure that out. Otherwise, I would read the git log and
compare it to Vigra's dependencies; you might find some clues. Then you
can use `git bisect` to narrow it down.

After installing libreoffice from that commit, you don't need to do
anything special. You can keep using guix normally. Your working
installation of libreoffice will remain in your profile until you can
successfully update it from the HEAD of the master branch again (that
is, with `guix pull`).

Ugh — figured it out — this was dumb on my part. I was running “$ sudo guix archive --authorize < signing-key.pub”, which obviously doesn't extend to input redirection — so nothing was authorized. 

Now I truly ran “# guix archive --authorize < signing-key.pub”, it authorized the key. 

Then I was able to import libreoffice to the store — the directory is there.

However, it's not installed in my profile — “guix package -I” doesn't list it. Running “guix package -i libreoffice” again wants to rebuild it. How do I install the one that's been imported to the store?

You have different package definitions on each machine. So, the
libreoffice you built is not the same as the one that would be built on
the destination machine, and so your binaries cannot be substituted.

If you are working out of git, with './pre-inst-env', then you should
make sure you are working from the same commit on both machines. This is
the easiest thing to do if you are trying to share substitutes between
machines. You don't have you run your whole system out of git; you can
just do it for the packages you wish to share.

Otherwise, if you are using `guix pull`, you will need to update both
machines, and possibly rebuild on the source machine if some part of the
libreoffice dependency graph has changed (likely).

There may be other options, but those are the two that I know.

You can run

    guix package -i /gnu/store/...-libreoffice-...

i.e. install the particular store item into your profile.
