Hi all,

a function 'fix_etc_hosts' in ipatests/test_integration/tasks.py produces incorrect /etc/hosts file (solitary IPv6 address), and currently parser is not able to resolve the issue, causing ipa-server-install to fail with 'list index out of range' error.

Hence I'm attaching patch to fix this issue before parser is fixed (related ticket to it #6014). The fix is just change of regexs responsible for creating incorrect file so that all the lines containing defined hostname are removed, not just specific IP/hostname/shortname strings.

Subject: [PATCH] Tests: Fix integration tests not to produce incorrect
 /etc/hosts file

Function 'fix_etc_hosts' in ipatests/test_integration/tasks.py produces incorrectly formatted /etc/hosts file (solitary IPv6 address), which causes ipa-server-install failure.
This provides fix of the function so that the regex changing /etc/hosts file remove entire lines with hostname entry in them.
