OK, with Torsten's and Alberto's input I did some cleanup, anyway that 740 default snapshot was very old and it was the default one, I'm a bit confused. So I have left things like this: raul@mordor:~$ sudo snapper ls # | Type | Pre # | Date | User | Used Space | Cleanup | Description | Userdata -----+--------+-------+--------------------------+------+------------+---------+-------------------+-------------- 0 | single | | | root | | | current | 843 | pre | | Fri Aug 16 22:52:27 2024 | root | 532.82 MiB | number | zypp(packagekitd) | important=yes 844 | post | 843 | Fri Aug 16 22:55:59 2024 | root | 1.36 MiB | number | | important=yes 845 | pre | | Fri Aug 16 22:57:07 2024 | root | 460.00 KiB | number | zypp(zypper) | important=yes 846 | post | 845 | Fri Aug 16 22:57:29 2024 | root | 956.00 KiB | number | | important=yes 847 | pre | | Sun Aug 18 00:35:09 2024 | root | 14.90 MiB | number | zypp(zypper) | important=no 848 | post | 847 | Sun Aug 18 00:36:20 2024 | root | 4.50 MiB | number | | important=no 849 | pre | | Mon Aug 19 00:07:05 2024 | root | 1.66 MiB | number | zypp(packagekitd) | important=yes 850 | post | 849 | Mon Aug 19 00:08:46 2024 | root | 2.08 MiB | number | | important=yes 851 | pre | | Mon Aug 19 00:28:56 2024 | root | 3.40 MiB | number | zypp(zypper) | important=yes 852* | post | 851 | Mon Aug 19 00:29:19 2024 | root | 16.34 MiB | number | | important=yes 853 | pre | | Mon Aug 19 14:58:05 2024 | root | 72.98 MiB | number | zypp(zypper) | important=yes 854 | post | 853 | Mon Aug 19 14:58:44 2024 | root | 3.88 MiB | number | | important=yes Eventually the snapshots 843-851 will age and will get autodeleted, 852 will be my default one. If there's something I should really correct, help is appreciated. I did run "sudo sdbootutil remove-kernel 6.10.3-1-default", however they directory still remained. If this part is under development, I understand that I was too fast to report this then. I removed the files manually for the time being, it looks like this now: mordor:~ # ls /boot/efi/bad01a2647cb4fef8827293b9d389245/ 6.10.4-1-default 6.10.5-1-default mordor:~ # rpm -qa | grep -i kernel-default kernel-default-6.10.4-1.1.x86_64 kernel-default-6.10.5-1.1.x86_64 So either you close this as invalid, or if you want to see what happens with the next kernel update, I can report here (in case my snapshots make sense, otherwise let me know how to fix them to look more useful). Thanks!
