Support, apparently I made a huge mistake or so, via the yast softwaremanagement, I went into that mode where I see the repositories on the left side each and every repo for itself. When clicking them, the yast listing the packages coming from that package. Some while ago, I added calibre ebook repo, from use user I think named ecsos or so, as that was the only repo I could kind of find via software.opensuse.org whose repo I could add to my 15.5 system that would then install me calibre. Anyhow, that repos brought in a set of other packages, I remember many python 3.11 or so packages being added as well. Today I wanted to simply delete or remove (red stop street road sign) in that yast software part. When trying to apply, the yast was doing dependency checks and it asked a few questions but not too many, oddly enough it asked e.g. I still remember if i wanted to keep or remove mozilla nss and so, which I have not messed with at all, dunno how this dependency came into play or how it was a chain of packages building on top of another and all being interconnected or something I suppose. Of course I kept all the packages that those questions asked by the yast software component. it even asked about openjdk or some weird stuff. I all kept those packages as I only remembered ticking off the python311 named packages in that ecsos repo with calibre. To the end before the yast software management started to run, it checked all those depending packages and eventually started off to work At the end, I kind of ended up with an empty KDE start menu and many of my pinned start symbols on the KDE tray or so (firefox, dolphin etc...) vanished or are now only a grey sheet symbol. Additionally the network (wifi) kind of turned itself off and vanishes, networkmanager or so seems gone, and even zypper ( i suppose /usr/bin/zypper ) doesnt come up any more. So quite a mess happened I didnt intend to I am so frustrated of myself and too liddle knowledge and experience. The affected system (15.5) is still up in KDE desktop, I can still fire up a konsole and e.g. midnightcommander and some stuff still works. To maybe make things worse? this system is full-disk-encrypted, just the normal way the 15.5 installer or was it the 15.4 installer back then offered with btrfs and snapshots. Could I simply reboot or turn off this system and maybe save my neck by reverting to a snapshot or something? I hope it did not kill the basic parts that I can boot somewhat into this fde grub menu and select an earlier snapshot there? i never tried this snapshot stuff before. This is kind of a hope, or any other hints on this matter? i can still attach an USB key to the machine although it doesnt automount it into the KDE session any more etc, but I guess i could make it work. maybe mount the 15.5 iso in some way and make the system repair somehow? i wouldnt know on how to fix the whole system step by step bringing in zypper or repos from the iso or whatnot? even wired ethernet seems to be off, no dhcp wise, although it still has a link and gets a linklocal ipv6 fe80: address or what that is called? but no ipv4 dhcp stuff and no global unicast ipv6 though. still zypper is gone or i dont find it? I compared a slowroll where zypper comes from there, but its not the same path on 15.5 or it is gone :( any good starters on this situation? thanks for any hints in helping me saving and repair this machine. ty.
