Comment:

 The branch bug14959-v1 in my repository has a patch to download missing
 versions:
 https://gitweb.torproject.org/user/boklm/tor-browser-
 bundle.git/commit/?h=bug14959-v1&id=418d84e33db2fbf411132f28c5d099ab4ff67eb7

 With this patch, when the directory for a version required to generate
 incremental MARs is not present, we download its sha256sums.txt from
 archive.tpo, check its signature, then download all .mar files and check
 that their checksum match the checksum from sha256sums.txt.

 It seems we didn't have the gpg public key used for signing Tor Browser
 releases in the repository, so the patch adds it in
 gitian/gpg/torbrowser.gpg.
