Sorry for the double post, I just didn't think anyone would answer my old question (Since it's old).
I'm having difficulty GPG-verifying my offline Armory installer for Ubuntu, using the suggested steps:
$ cd Downloads # the directory containing the *.deb
$ gpg --recv-keys --keyserver keyserver.ubuntu.com 98832223
$ sudo apt-get install dpkg-sig
$ dpkg-sig --verify *.deb
The first three steps are working, since I can verify the standard Ubuntu installer:
ubuntu@ubuntu:~/Downloads$ dpkg-sig --verify *.deb
Processing armory_0.92.3_ubuntu-32bit.deb...
GOODSIG _gpgbuilder 821F122936BDD565366AC36A4AB16AEA98832223 1412393663
But for the offline bundle I just get this:
ubuntu@ubuntu:~/Downloads$ dpkg-sig --verify *.deb
E: Cannot find *.deb: no such file
ubuntu@ubuntu:~/Downloads$ ls
Alan-C.-Reiner-Offline-Signing-Key-alan@bitcoinarmory.com-0x98832223-pub.asc armory_0.92.3_offline_ubuntu_12.04-32.tar.gz
So I extracted the .tar.gz and cd OfflineBundle, which gives me these files:
ubuntu@ubuntu:~/Downloads/OfflineBundle$ ls
Alan-C.-Reiner-Offline-Signing-Key-alan@bitcoinarmory.com-0x98832223-pub.asc armory_0.92.3_ubuntu-32bit.deb

I'm pretty sure it's armory_0.92.3_ubuntu-32bit.deb that is the file that should have the GOODSIG after it, but when I run dpkg-sig --verify *.deb, I just get this:

Am I missing something? What should I do? I'm almost tempted to just replace the armory_0.92.3_ubuntu-32bit.deb file that came in the offline bundle with the one that came with the standard armory installer, but I'm worried that the rest of the files in OfflineBundle may have been tampered with as well.
