Hi, some days ago I attempted to upgrade our Uyuni system again and this time I was more lucky than in the past. The upgrade path was 2020/04 on opensuse-15.1 to 2020/09 (on opensuse-15.2). The procedure is described at the end of the mail. Since the upgrade there are two issues: 1.) During the daily sync of the repositories (SLES15-SP1 and SLES15-SP2) the system reports messages at the Web-GUI for every channel like this one: Creating Bootstrap Repository failed Error generating bootstrap repo for: SLE-15-SP2-x86_64 "Details" show: ERROR: package 'python3-hwdata' not found ERROR: package 'python3-rhnlib' not found ERROR: package 'spacewalk-check' not found ERROR: package 'spacewalk-client-setup' not found ERROR: package 'spacewalk-client-tools' not found ERROR: package 'python3-spacewalk-check' not found ERROR: package 'python3-spacewalk-client-setup' not found ERROR: package 'python3-spacewalk-client-tools' not found ERROR: none of 'mgr-daemon', 'spacewalksd' found ERROR: package 'suseRegisterInfo' not found ERROR: package 'python3-suseRegisterInfo' not found ERROR: package 'zypp-plugin-spacewalk' not found ERROR: package 'python3-zypp-plugin-spacewalk' not found The synchronization of the channels seems to be successful as there are reports of new patches. The updates of the clients work fine, too. 2.) The usage of shared memory has increased significantly since the upgrade. 24 h after restart of the PostgreSQL-DB its level is nearly 2 GB which is 25%. ipcs says that this is the only process using it. Is this normal? Does the system need more memory? FYI - the upgrade was done according to https://www.uyuni-project.org/doc/2020.09/uyuni_upgrade_guide.pdf with these tasks in short (leaving out backup and snapshot of the system powered off): (Enabling all repositories) spacewalk-service stop zypper ref zypper up susemanager /usr/lib/susemanager/bin/server-migrator.sh /usr/lib/susemanager/bin/pg-migrate-10-to-12.sh fast reboot Thanks for any hints!
