Question: purging a package from the store

Question: purging a package from the store

[Pjotr Prins]

Our caching server gives a consistent failure for one package. It
exists in the store and 'guix gc checks' pass.

  guix substitute: error: download from
  'http://guix.genenetwork.org:8080/nar/sqd3q1xq5fsbga00bwhghi9shi7xdaac-gtk+-3.18.2'
  failed: 404, "Not Found"

Now I want to purge it without running a full gc. Next reinstall it
and see if it gets fixed.

What is the suggested method for fully purging a package from the store?

Pj.

What about:
  guix gc --delete /gnu/store/...-gtk+-3.18.2/

(add the specific package path after --delete).

A package can only be purged when it is not installed in any profile.

Kind regards,

Hmmm. It is a running server that actually uses that package.

I wonder if it is the same problem we saw before on the substitute
servers (hits missing). How did we resolve those? What was the real
problem? A rebuild merely reinstates the profile on this machine. It
actually appears to be fine.

Even so the nar server gives an error for this package. Only for this
package - all others are served.

I guess I have to read some source code.

It looks a lot like <http://bugs.gnu.org/21888>, which we should really
fix now.

Good to see you’re running your own service!

It is used for GeneNetwork - a complex web service. It uses git for
byte-identical installs and a Guix server for distributing the
binaries. This is my current way to making sure everyone is running
the exact same software tree and get binary installs.

The installation notes are here:

  https://github.com/pjotrp/genenetwork2/blob/paper/doc/README.org#quick-installation-recipe

It is not as easy as 'guix package -i genenetwork2'. But then, it
works (TM). People are installing it this way.

Nice!  One limitation that may be a problem for you is that ‘guix
publish’ doesn’t yet compress the archives it serves.

Is there anything particular preventing you from writing a genenetwork2
package?

Thanks,

The package exists, but I can't push it to Guix.  Some software in
there is not properly licensed. I'll need to approach the authors
one-by-one.

We may get there eventually if anyone is interested.

Confirmed. The bug is fixed, even running publish on the 'wrong' locale.

Many thanks!

Great!

Also, you can now run:

  guix publish --ttl=3d

if you want to make sure users don’t see “updating the list of
substitutes” too often.  ;-)

But see the note in the manual about it.
