Changes for GnuPG in debian

Recommended Posts

Short version (TL;DR)

=====================

 

/usr/bin/gpg will soon be provided by GnuPG's "modern" branch (2.1.x)

and the "classic" branch (1.4.x) will be available as /usr/bin/gpg1

 

The rest of this e-mail provides details for users of GnuPG and package

maintainers.

 

For more about the rationale and benefits, see

https://debian-administration.org/users/dkg/weblog/116.

 

 

 

Details below:

 

What does this mean for users of GnuPG?

---------------------------------------

 

Even if you use GnuPG regularly, you shouldn't notice too much of a

difference. One of the main differences is that all access to your

secret key will be handled through gpg-agent, which should be

automatically launched as needed. This means that operations like

signing and decryption will cause gpg-agent to prompt the the user to

unlock any locked keys directly, rather than gpg itself prompting the

user.

 

If you have an existing keyring, you may also notice a difference

based on a change of how your public keys are managed, though again

this transition should ideally be smooth enough that you won't notice

unless you care to investigate more deeply.

 

If you use GnuPG regularly, you might want to read the NEWS file that

ships with GnuPG and related packages for updates that should help you

through the transition.

 

If you use GnuPG in a language other than English, please install the

`gnupg-l10n` package, which contains the localization/translation

files. For versions where those files are split out of the main

package, `gnupg` explicitly `Recommends: gnupg-l10n` already, so it

should be brought in for new installations by default.

 

If you have an archive of old data that depends on known-broken

algorithms, PGP3 keys, or other deprecated material, you'll need to

have "classic" GnuPG around to access it. That will be provided in

the `gnupg1` package

 

What does this mean for package maintainers?

--------------------------------------------

 

If you maintain a package that depends on `gnupg`: be aware that the

`gnupg` package in debian is going through this transition.

 

A few general thoughts:

 

* If your package `Depends: gnupg` for signature verification only,

you might prefer to have it `Depends: gpgv` instead. `gpgv` is a

much simpler tool that the full-blown GnuPG suite, and should be

easier to manage. I'm happy to help with such a transition (we've

made it recently with `apt` already)

 

* If your package `Depends: gnupg` and expects `~/.gnupg/` to be laid

out in a certain way, that's almost certainly going to break at

some point. `~/.gnupg/` is GnuPG's internal storage, and it's not

recommended to rely on any specific data structures there, as they

may change. `gpg` offers commands like `--export`, `--import`, and

`--delete` for manipulating its persistent storage. please use them

instead!

 

* If your package depends on parsing or displaying `gpg`'s output for

the user, please make sure you use its special machine-readable

form (`--with-colons`). Parsing the human-readable text is not

advised and may change from version to version.

 

If you maintain a package that depends on `gnupg2` and tries to use

`gpg2` instead of `gpg`, that should stay ok. However, at some point

it'd be nice to get rid of `/usr/bin/gpg2` and just have one expected

binary (`gpg`). So you can help with that:

 

* Look for places where your package expects `gpg2` and make it try

`gpg` instead. If you can make your code fall back cleanly

 

* Change your dependencies to indicate `gnupg (>= 2)`

 

* Patch `lintian` to encourage other people to make this switch ;)

 

What specifically needs to happen?

----------------------------------

 

The last major step for this transition was renaming the source

package for "classic" GnuPG to be `gnupg1`. This transition is

currently in the ftp-master's NEW queue. Once it makes it through

that queue, and both `gnupg1` and `gnupg2` have been in experimental

for a few days without reports of dangerous breakage, we'll upload

both `gnupg1` and `gnupg2` to unstable.

 

We'll also need to do some triage on the BTS, reassigning some reports

which are really only relevant for the "classic" branch.

 

Please report bugs via the BTS as usual! You're also welcome to ask

questions and make suggestions on #debian-gnupg on irc.oftc.net, or to

mail the Debian GnuPG packaging team at

pkg-gnupg-maint ( -at -) lists.alioth.debian.org.

 

Happy hacking!
