Hello Diko, or anyone else affected,

Accepted nova into jammy-proposed. The package will build now and be

hours, and then in the -proposed repository.

Please help us by testing this new package.  See

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, what testing has been
performed on the package and change the tag from verification-needed-
jammy to verification-done-jammy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-jammy. 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

Bug description:
  [Impact]
  Charm revision: 320
  Cloud: bionic-ussuri

  Permissions 0644 for '/var/lib/nova/.ssh/id_rsa' are too open.
  Load key "/var/lib/nova/.ssh/id_rsa": bad permissions
  nova at 10.35.80.49: Permission denied (publickey).

  This was preventing nova resizing:

  /var/log/nova/nova-compute.log:2020-11-17 13:14:42.210 100221 ERROR
  oslo_messaging.rpc.server Command: ssh -o BatchMode=yes 10.35.80.49
  mkdir -p /var/lib/nova/instances/39caee98-b81c-4cef-9810-815f2ecf1fc4

  Manually setting to 0600 fixed the issue.

  Note (coreycb): It's important to note that /var/lib/nova/.ssh/ and
  files contained in that directory are not created by the package.
  Therefore the package should avoid changing permissions for this
  directory.

  [Test Case]
  Install a previous version of the nova-common package.
  Setup ssh as described here (at least the creation of /var/lib/nova/.ssh/ files and chmod accordingly): https://docs.openstack.org/nova/pike/admin/ssh-configuration.html
  Upgrade to the patched version of nova-common and confirm the /var/lib/nova/.ssh/ directory/file modes haven't changed.

  [Regression Potential]
  This is actually fixing a regression that was introduced to the package when we introduced the postinst code that does a blanket chmod to all of /var/lib/nova/. Assuming the test case above passes, I can't see any way for this to cause another regression.
