I tried starting a similar trusty chroot that had the extension and unity targets installed, and it failed to start (with the same error) as well. This chroot I'm starting does _not_ have the extension target installed, just unity. It had no trouble installing, and I am able to do sudo enter-chroot to enter the trusty chroot via command line. The following is the terminal output. I tried updating both the crouton script file and the trusty chroot (no errors reported), neither of which solved the issue. I ran croutonversion on the chroot as well, so I believe I followed all guidelines in https://github.com/dnschneid/crouton/wiki/Common-issues-and-reporting. :smile: \r\n\r\n```\r\nWelcome to crosh, the Chrome OS developer shell.\r\n\r\nIf you got here by mistake, don't panic!
