URL: https://github.com/SSSD/sssd/pull/504 Author: lslebodn Title: #504: Remove legacy script for upgrading sssd.conf Action: opened
PR body: """ The script was mainly required to upgrade sssd.conf from version 1 to version 2 which was done in sssd-0.6. All currently supported linux distribution have at least sssd >= 1.8 and require 2nd version of sssd.conf. Therefore upgrade does not make any sense. There was an attempt to port this file to python3 as part of ticket#2017 3 years ago. But it does not work and nobody noticed that due to missing code coverage. sh# ls -l /etc/sssd/sssd.conf -rw-------. 1 root root 5372 Jan 24 21:09 /etc/sssd/sssd.conf sh# python3 -m SSSDConfig.sssd_upgrade_config ERROR: a bytes-like object is required, not 'str' sh# ls -l /etc/sssd/sssd.conf -rw-------. 1 root root 0 Jan 24 21:09 /etc/sssd/sssd.conf Summary: The script does not make any sense today, it is not used by anyone and therefore it does not worth to keep it in upstream any more.
