Hello Daniel, or anyone else affected,

Accepted gce-compute-image-packages into trusty-proposed. The package
will build now and be available at https://launchpad.net/ubuntu/+source
/gce-compute-image-packages/20180905+dfsg1-0ubuntu1~14.04.1 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-trusty to verification-done-trusty. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-trusty. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Bug description:
  SRU Justification
  =================

  [Impact]
  oslogin fails on Xenial and Trusty.

  In auth.log we see:

  Oct 17 16:35:59 davecore-oslogin sshd[10073]: PAM unable to dlopen(pam_oslogin_login.so): /lib/security/pam_oslogin_login.so: cannot open shared object file: No such file or directory
  Oct 17 16:35:59 davecore-oslogin sshd[10073]: PAM adding faulty module: pam_oslogin_login.so
  Oct 17 16:35:59 davecore-oslogin sshd[10073]: PAM unable to dlopen(pam_oslogin_admin.so): /lib/security/pam_oslogin_admin.so: cannot open shared object file: No such file or directory
  Oct 17 16:35:59 davecore-oslogin sshd[10073]: PAM adding faulty module: pam_oslogin_admin.so

  The error message is a bit deceptive - PAM tries to load the module
  from the correct location, fails, and then tries the other location
  where it is missing. It then reports the missing error rather than the
  real error.

  symlink the module into both paths leads to a much more useful error
  message:

  [Test case]
   - set up GCE VM
   - turn on oslogin
   - attempt to log in

  [Fix]
  debian/patches/0002-Set-LDFLAGS-at-the-end-of-the-c-command-line-right-b.patch re-orders the link flags to link boost_regex for oslogin. However, this didn't change the flags for PAM module linking. So fix that too.

  [Regression Potential]
  - fixes a regression
  - limited to oslogin, and how it is linked.

  [Other Notes]
  We still see a scary list of warnings when building, but they don't seem to have an impact on the common path:
