I tried to use the online upgrade function to go from Leap 15.6 to TW, folling the guide, using the commands given. Things went smoothly, it asked me to confirm if i want to update the packages and such, I say yes, it does its thing. It stops and asks if I want to overwrite some files, which I say yes to, and it does its thing. The commands finish, and it tells me to reboot. I do so. After I rebooted I’m sitting at a kernel terminal.
I dont know how to get back to my desktop, I dont know what went wrong, the guide has no additional notes other than about PAM or refreshing zypper. I tried that, and got an error.
It says: “zypper: symbol lookup error: /lib64/libprotobuf-lite.so.25.1.0: undefined symbol: _ZN4absl12lts_2024011612lpg_internal15LogMessageFatalC1EPKciNS0_11string_viewE”
I cant find anything online about this error, so I dont know what I have to do. Im sorry I cant give more info, I just dont have anything else to say about what I did, i followed instructions to a T.
Something happened to me similar to this 3-4 times doing 15.6 beta upgrades months ago. Each time I succeeded to repair via a combination of copying the prior zypper binary with installing matching rpm packages that alter the dependency, details of which I no longer remember.
Once zypper works through the use of rpm, the upgrade can be completed with zypper. Using rpm you can see which versions of the applicable packages have been installed, and which on the mirrors still need to be.
If you’re not keen on use of rpm and/or manual package fetching, you still have the option to use a TW installation .iso to upgrade what you have to current TW. Since most of upgrade is probably done, I recommend using the little TW NET installation .iso to get the probably few packages needed for a complete working TW.
Was your 15.6 current with updates?
