New subject: ipa-restore: a bytes-like object is required, not 'str'

22 Jan 2018


      On a fresh installed IPA server where I do a backup and restore right after installation I get:
a bytes-like object is required, not 'str'
The ipa-restore command failed. See /var/log/iparestore.log for more information
