[ChristianEhrhardt]

On just rerunning the tests s390 and ppc worked this time.
Arm failed again but at another test - retrying again.
I really start to assume ubuntu-image has a noisy test even not knowing it.

[ChristianEhrhardt]

Thank Brian for the ping here,
Of the issues found in the logs none seem all too multipath specific, seems 
mostly:
- ERROR: InterpreterNotFound: python3.6
- sha3-384 mismatch for "pc-kernel"
- and a bunch of file not found for various .img files

I wonder if the latter issues are due to the missing python3.6.
Overall - so far - it appears to be more issues in the ubuntu-image tests than 
multipath issues.
Are these known issues in ubuntu-image or is the assumption of anyone that 
multipath really broke something here?

This new version of multipath-tools is failing to migrate in artful, due
to autopkgtest failures.

[Andy Whitcroft]

Hello Mauricio, or anyone else affected,

Accepted multipath-tools into zesty-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/multipath-
tools/0.6.4-3ubuntu4 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 to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

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

[Bug 1682178] Re: multipathd.socket unit fails to start ("Failed to listen on sockets: Address already in use")

[Mathieu Trudel-Lapierre]

** Description changed:

+ 
+ [Impact]
+ Multipath users on Ubuntu Server will see error messages from multipathd at 
boot. While the system continues to boot and is in a stable state, multipathd 
should be appropriately handled via its systemd unit after the system is booted.
+ 
+ [Test case]
+ 1) Install with multipath enabled (disk-detect/multipath/enable=true).
+ 2) Boot the installed system
+ 3) Verify that there are no error messages from multipathd at boot.
+ 
+ [Regression potential]
+ This update changes the startup/shutdown login in initramfs at an early boot 
state, this could lead to failures to complete the booting process for systems 
that depend on multipath being available to bring up the rootfs, or failure to 
correctly drive multipathd/multipath-tools from a booted system. Furthermore, 
failures or delays shutting down a system due to multipathd / multipath-tools 
remaining up should also be considered as possible regressions issued from this 
update. 
+ 
+ ---
+ 
  This bug is used to include one more patch to completely fix LP 1670811.
  
  That patch is mentioned in LP 1670811 comment 15 [1].
  
  It addresses the case in which the initramfs instance of multipathd
  takes a while to actually shutdown after its receives the signal from
  initramfs/scripts/local-bottom/multipath.
  
  That shutdown is asynchronous, and keeps the multipathd socket open.
  If it is still open by the time the root fs is mounted and its units are 
started, the multipathd.socket will fail to start.
  
  Patch attached.
