Hi, I use the following steps to upgrade each OTRS patch Version on Fedora: sudo -i systemctl stop crond.service systemctl stop httpd.service Run the following as "otrs" user: su - otrs /opt/otrs/bin/Cron.sh stop /opt/otrs/bin/otrs.Daemon.pl stop exit Run the following as "root": cd /opt ls rm otrsrpm.rpm -f ls curl http://ftp.otrs.org/pub/otrs//RPMS/rhel/7/otrs-6.0.26-01.noarch.rpm -Lo /opt/otrsrpm.rpm ls rpm -Uvh /opt/otrsrpm.rpm systemctl start httpd.service systemctl start crond.service Run the following as "otrs" user: su - otrs /opt/otrs/bin/otrs.Daemon.pl start /opt/otrs/bin/Cron.sh start After installing the patch, I was no longer able to enter my username and password to log into OTRS. No idea why. Just in case others have the same issue, used the following to revert to the previous version OTRS 6.0.25: Same steps as above, but with curl http://ftp.otrs.org/pub/otrs//RPMS/rhel/7/otrs-6.0.25-01.noarch.rpm -Lo /opt/otrsrpm.rpm rpm -Uvh --oldpackage /opt/otrsrpm.rpm I have tried this a couple of times, going back and forth, and it has worked in each case. Upgrading to patch level 26 results in my no longer being able to log on to OTRS, reverting back to patch level 25 allows me to keep on working in OTRS. Regards Rudolf Bargholz
