Guest agent won't start on Ubuntu Xenial Percona 5.7 image

[Gaëtan Trellu]

Trove guest agent on Ubuntu Xenial Percona 5.7 image won't start because of a missing header in "/etc/mysql/my.cnf" file.

Trove guest agent error log:

ERROR root raise MissingSectionHeaderError(fpname, lineno, line)
ERROR root MissingSectionHeaderError: File contains no section headers.
ERROR root file: <???>, line: 3
ERROR root '!includedir /etc/mysql/conf.d/\n'

Same issue as for MySQL 5.7 on Ubuntu Xenial: https://bugs.launchpad.net/trove/+bug/1645921

    Guest agent won't start on Xenial Percona 5.7

    Trove guest agent on Ubuntu Xenial Percona 5.7 image won't start
    because of a missing header/section in "/etc/mysql/my.cnf" file.

    To fix that, we only have to check if a section exists, if not
    a [mysql] section is automatically created.

I believe this won't work because the file permissions for the new element 10-fix-mycnf are not executable. File permissions for elements should be 775. This is just a quirk of the mechanism.

This issue was fixed in the openstack/trove 9.0.0.0b3 development milestone.
