The fix just published now and I confirmed that my affected machines are now upgrading fine.

With version 10 I get the same error as Maki Kato above at #4:

Seems like a missing "then" after the first "if" in <preinst>.

[Isaac Mercer (nos-developer)]

Can confirm that ubuntu11 is up and has fixed this.

[Chris Kankiewicz (phlak)]

Seems good now. Thanks.

[Cip Man (cipman-p)]

Yes, version 11 fixed it. Thank you.
