pull-lp-debs fails to download single binary package for foreign architecture

Status changed to 'Confirmed' because the bug affects multiple users.

I had the same issue when trying to download the binary packages for a raspi device:

$ uname -m
x86_64
$ pull-lp-debs --arch arm64 linux-buildinfo-6.8.0-1004-raspi
Source package lookup failed, trying lookup of binary package linux-buildinfo-6.8.0-1004-raspi
The binary package 'linux-buildinfo-6.8.0-1004-raspi' does not exist in the Ubuntu primary archive for architecture amd64 in any release for pockets Release, Security, Updates, Proposed with status in Pending, Published
The source package 'linux-buildinfo-6.8.0-1004-raspi' does not exist in the Ubuntu primary archive in any release for pockets Release, Security, Updates, Proposed with status in Pending, Published

The issue seems to be that the `arch` parameter is not being parsed to the `getBinaryPackage()` function:

$ pull-lp-debs -a arm64 linux-buildinfo-6.8.0-1004-raspi
Source package lookup failed, trying lookup of binary package linux-buildinfo-6.8.0-1004-raspi
The archtag used in getBinaryPackage() is: None

The source package 'linux-buildinfo-6.8.0-1004-raspi' does not exist in the Ubuntu primary archive in any release for pockets Release, Security, Updates, Proposed with status in Pending, Published

After parsing the args to the `getBinaryPackage()` function, the issue is solved:

$ pull-lp-debs -a arm64 linux-buildinfo-6.8.0-1004-raspi
Source package lookup failed, trying lookup of binary package linux-buildinfo-6.8.0-1004-raspi

This bug was fixed in the package ubuntu-dev-tools - 0.206

---------------
ubuntu-dev-tools (0.206) unstable; urgency=medium

  [ Dan Bungert ]
  * mk-sbuild: enable pkgmaintainermangler

  [ Shengjing Zhu ]
  * import-bug-from-debian: package option is overridden and not used

  [ Fernando Bravo Hernández ]
  * Parsing arch parameter to getBinaryPackage() (LP: #2081861)

  [ Simon Quigley ]
  * Read ~/.devscripts in a more robust way, to ideally pick up multi-line
    variables (Closes: #725418).
  * mk-sbuild: default to using UTC for schroots (LP: #2097159).
  * syncpackage: s/syncblacklist/syncblocklist/g
  * syncpackage: Cache the sync blocklist in-memory, so it's not fetched
    multiple times when syncing more than one package.
  * syncpackage: Catch exceptions cleanly, simply skipping to the next
    package (erring on the side of caution) if there is an error doing the
    download (LP: #1943286).
