Something wrong with Plesk distribution server? cpio md5 errors

[HostaHost]

For the past few weeks, adding components to Plesk via autoinstaller more often than not produces errors like these on the first attempt:

error: unpacking of archive failed on file /etc/init.d/pc-remote;52e2a8c6: cpio: MD5 sum mismatch

That was converting a centos 5 i386 server from qmail to postfix, but it's not limited to just postfix or the OS; I see the same thing adding pieces to centos 6, i386 and x86_64, etc. Typically running the same attempt a few more times will finally get it to work, so perhaps some server within the Parallels' CDN has corrupt files.
