I also see this bug, but I think enigmail is actually noticing the message is signed - if I disable automatic message verification/decryption, I get a message "Possibly PGP/MIME encrypted or signed message; click Decrypt button to verify". Of course, there is no "decrypt" button visible to click.

I also have display mail user agent installed, so I thought it might be an interaction with that; disabling that extension doesn't seem to affect that bug.

This is for Ubuntu 10.04 (Lucid) on amd64.

I can confirm this bug on Lucid amd64.
I also have the "mail user agent extension" installed.

I seem to have the same bug with enigmail on lucid., x86_64. If I install enigmail from, it works properly.

Tobias Beck (vitrex) wrote :

Workaround #4 worked for me.

- Uninstall enigmail package
- Download xpi
- Install it over Addons in Thunderbird

Pete Stephenson (heypete) wrote :

Also confirmed on 64-bit Lucid.

PGP/MIME signatures work fine with encrypted+signed messages, but are not detected on signed-only messages.

do you get any errors in the tools -> error console when opening such a message? (or in general?)

Further to #4, #5: enigmail 1.0.1 as installed via apt is broken, enigmail 1.0.1 downloaded from Mozilla is OK, so it's an Ubuntu problem. b.t.w no need to uninstall the Ubuntu version, just disable it in add-ons before installing the official Mozilla one.

Is the fix going to be backported to Lucid?

This will be fixed in Maverick when we update to Enigmail 1.1.2. This will also be backported to Lucid when we update to Thunderbird 3.1 later this year.

This bug was fixed in the package enigmail - 2:1.1.2-0ubuntu1

enigmail (2:1.1.2-0ubuntu1) maverick; urgency=low

  * New upstream release

  * Merge from debian unstable. Remaining changes:
    - Drop versioned mozilla-devscripts dependency since we don't build on
      mips or mipsel
    - Add back thunderbird-dev build depends
      - update debian/control
    - fixes LP: #565014 - No signature detected in emails signed using pgp/mime

  * Update build-depends on thunderbird or icedove to >= 3.1~
    - update debian/control
  * Drop frozen_api patch as changes were accepted upstream
    - drop debian/patches/frozen_api.diff
    - update debian/patches/series
  * Use system NSPR in Ubuntu as well
    - update debian/rules
  * Build with -fshort-wchar for now to make the build succeed
    - update debian/rules

enigmail (2:1.0.1-5) unstable; urgency=low

  * Update frozen_api.diff to include nsEnigMimeListener.cpp and
    nsEnigMimeService.cpp versions matching current upstream CVS. This fixes
    PGP/MIME parsing. closes: #586577
  * Pass --disable-optimize to configure script if called with noopt in
  * Call the distclean target of all Makefiles that support it. This allows to
    significantly reduce the number of files in debian/clean. Still there are
    some generated python build scripts.

enigmail (2:1.0.1-4) unstable; urgency=low

  * Explicitly set target machine type according to dpkg-architecture
    (DEB_BUILD_GNU_TYPE) to allow building working versions of the i386
    package in i386 chroot with amd64 kernel.
  * Add -std=gnu++0x to CXXFLAGS in order to allow building with icedove
    3.0.5-1. closes: #586860, thanks to Christoph Goehre for this hint.

enigmail (2:1.0.1-3) unstable; urgency=low

  * Remove Build-Dependency on libiw-dev. This is not used, but configure now
    requires --disable-necko-wifi to be happy. Should allow build on kfreebsds.
  * Build-Depend on mozilla-devscripts >= 0.23 to really fix FTBFS on mipsel
    and mips. (m-d changed RDF implementation used to parse install.rdf)

enigmail (2:1.0.1-2) unstable; urgency=low

  * Patch makefile-in-empty-xpcom-fix.diff: Fix FTBFS on armel, mips,
    and mipsel.

enigmail (2:1.0.1-1) unstable; urgency=low

  * Upload based on Ubuntu package:
    - New upstream version closes: #569804, #461643, #553272
  * Fix RC Bugs:
    - enigmail < 1.0 not supported in icedove >= 3. closes: #569804, #562714
    - enigmail 0.95 no longer builds. closes: #576997
  * Use build flags --with-system-nspr --with-nspr-prefix=/usr if debian
    environment is detected (detection as proposed in bug #569804)
  * According to asac, buildds cannot cope with alternatives in
    Build-Depends. Thus drop thunderbird-dev alternative.
  * Some files are not removed at clean time. Added to debian/clean, so
    deleted by debhelper.
  * lintian:
    - fix description-starts-with-package-name
    - Fix 3 consecutive changelog entries: syntax-error-in-debian-changelog
      (wrong date format)
    - Add README.source for quilt: patch-system-but-no-source-readme
  * Add myself to Uploaders.
