[Bug 1686045] Re: Upgrade from 16.10 to 17.04 failed due to missing ./xorg_fix_proprietary.py

[Brian Murray]

In main.log we can see the following:

2017-04-25 09:02:05,146 DEBUG failed to SystemUnLock() (E:Not locked) 
2017-04-25 09:26:33,669 ERROR got an error from dpkg for pkg: '/tmp/apt-dpkg-install-DzqcXg/0364-libgtest-dev_1.8.0-6_amd64.deb': 'subprocess new pre-installation script returned error exit status 1'

    res = pm.do_install(self.writefd)
apt_pkg.Error: E:Sub-process /usr/bin/dpkg returned an error code (1)

apt-term.log then provides more information about what went wrong with
libgtest-dev:

dpkg-maintscript-helper: error: directory '/usr/src/gtest' contains files not owned by package libgtest-dev:amd64, cannot switch to symlink
dpkg: error processing archive /tmp/apt-dpkg-install-DzqcXg/0364-libgtest-dev_1.8.0-6_amd64.deb (--unpack):
 subprocess new pre-installation script returned error exit status 1

Do you know what is in that folder "/usr/src/gtest"?
