See question and linked answer at http://serverfault.com/a/831169/15756, also comment 18 by Rocko on #1571865 @ https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1571865/comments/18, referenced by the blog post referenced by the answer to the serverfault question. He was asked to created a new bug but did not have the time - please regard this as the bug report.

1) lsb_release -rd:

2) apt-cache policy mysql-server:

3) I expected to be able to install mysql as part of a vagrant provisioning script without having to jump through Ubuntu specific hoops.

4) `apt-get install -y mysql-server mysql-client` hung and stalled my build pipeline until I added the line `(sleep 200; killall mysqld)&` to my provisioning script right before that line. This makes me very uncomfortable - I should never have to kill a setup task.

Thank you for taking the time to report this bug and helping to make Ubuntu better.

I cannot reproduce this. I tried installing mysql-server 5.7.17-0ubuntu0.16.04.1, purged mysql* and installed again, and it worked without error.

Please can you either post exact steps to reproduce your problem, or identify what it is that is hanging and at what step? Once you have provided this information please change the bug status back to New. Thanks!
