+Subject: [PATCH] [ubuntu|Policy] Fix exception when attempting upload
+
+Fixes an issue where an upload attempt on Ubuntu systems would fail with
+a traceback due to the upload archive's name not being available when we
+first check to make sure we have an upload location, since the Ubuntu
+default location requires an archive/file name.
+
+Related to this, stop clobbering `upload_archive` and assign the archive
+name to an `upload_archive_name` variable instead.
+
+Closes: #2472
+Resolves: #2479
