            Bug ID: 221266
           Summary: [webkitcorepy] Autoinstaller can fail on packages
                    containing write protected files
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: don.olmstead at sony.com

This is kind of a fringe issue that I've had happen to me a few times. One of the packages, logilab.common, contains a write-protected file. Looks like if an autoinstall of a package fails the temp directory the tar is extracted to is still present. When the install is run again the tar can't be extracted because the write protected file is present and its being written to.

Traceback (most recent call last):
