In Ubuntu 17.04 : after reboot getting message in console like Unable to open file: /etc/keys/x509_ima.der (-2)

*** Bug 150629 has been marked as a duplicate of this bug. ***

That is likely a correct assesment, I assume correctly functioning IMA requires some user space packages ? Especially one that will create /etc/keys/x509_ima.der and /etc/keys/x509_evm.der

I would assume that the keys are generated by the emvctl package. This would require evmctl tools packaged in Ubuntu. Could you please confirm that this package might be a likely candidate that we might want to carry in Ubuntu? https://sourceforge.net/p/linux-ima/ima-evm-utils/ci/v0.9/tree/

This bug is not fixed by packaging the IMA tools, which would still not be configured/enabled by default. The bug here is that an error message is presented on the console, by default, about an optional feature that has not been enabled. That's a kernel bug.

This seems like a legitimate warning and not really a bug.

Unfortunately this message does not seem as a warning, but, as an error.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-yakkety' to 'verification-done-yakkety'. If the problem still exists, change the tag 'verification-needed-yakkety' to 'verification-failed-yakkety'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
