After two failed Leap 16.0 upgrades, I used Gemini AI to help me draft a check-off list to successfully make this upgrade. I first of all have to replace my Nvidia GeForce GT710 video card, I have a Radeon RX-550 card ordered and I will make sure that this is running okay in Leap 15.6 and delete the Nivida repository.
After that, here is the check list:
=== LEAP 15.6 TO 16.0 MIGRATION PROTOCOL ===
File Reference: update-leap.txt
PHASE 1: PREPARATION (Inside the Graphical Desktop)
--------------------------------------------------------------------------------
1. Take a snapshot of all currently installed package versions:
sudo rpm -qa --qf "%{NAME}-%{VERSION}-%{RELEASE}.%{ARCH}\n" | sort > /root/packages_before_upgrade.txt
2. Freeze and backup your current Leap 15.6 repository configurations:
sudo /root/repo-manager.sh backup
3. Manually disable all third-party repositories to prevent dependency locks:
sudo zypper mr -d packman brave_browser code google-chrome opera NVIDIA:repo-non-free.repo_1 lynis home_maxiotis
4. Take your pristine Snapper baseline snapshot (Note the ID number it prints!):
sudo snapper create --type pre --print-number --description "Latest Leap 15.6" --cleanup-algorithm number
PHASE 2: TRANSITION TO THE CLI (Virtual Consoles)
--------------------------------------------------------------------------------
5. Drop to a raw text terminal by pressing: Ctrl + Alt + F2
Log in directly as the 'root' user.
6. Cleanly isolate the system and kill the graphical desktop session completely:
systemctl isolate multi-user.target
PHASE 3: THE UPGRADE EXECUTION
--------------------------------------------------------------------------------
7. Set up the live background error tracking:
- Press Ctrl + Alt + F3 to open a second terminal.
- Log in as 'root'.
- Run the following command to track systemd journal errors in real-time:
journalctl -f -p 3 -o short-precise > /root/migration_journal.log
8. Launch the migration tool with persistent session logging:
- Press Ctrl + Alt + F2 to switch back to your first terminal window.
- Execute the migration utility:
opensuse-migration-tool 2>&1 | tee /root/migration_attempt.log
PHASE 4: POST-MIGRATION / CONTINGENCY RECOVERY
--------------------------------------------------------------------------------
9. If the migration tool finishes cleanly with no errors:
reboot
10. If the machine fails to boot or crashes during the subsequent reboot:
- Boot using a recovery USB or select a read-only snapshot from the GRUB menu.
- Drop to a command line and pull the crash log from the failed boot attempt immediately:
sudo journalctl -b -1 > /root/previous_boot.log
11. If you need to roll back and restore your 15.6 repositories after a filesystem revert:
sudo /root/repo-manager.sh restore
================================================================================
Is there anything I am missing or overlooking? I do want solid logs in case this upgrade fails.
I appreciate comments by the openSuse Linux gurus.
