well this is the problem i have really no idea why it went into a situation where it removed by firefox example etc. I only unticked those python311 prefixed/named packages on that one repo inside the yast software module.

...

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?

Absolutely, revert to the snapshot made just before your yast operation. You can check before rebooting what snapshots you have.

so after the first password unlock of fde, then the grub2 menu showing up, I select some snapshot listed there or how would this work or where does this show up exactly? then the second password entry to actually boot would come along, right?

Alternatively, look in the log what packages were removed and install them back. All of them, one by one.

/var/log/zypp/history

Another possibility is to boot from the installation full DVD or USB, then choose upgrade installed system.

can the 15.5 iso image with its install module use and mount the apready present fde situation of the disk? i really hope so, i already thought about this. in the past, without using fde, i sometimes used to install onto/into the already present and existing opensuse system of the same version e.g. 15.3 iso booting and installing over 15.3 opensuse present on disk already. it would then kind of repair, replace or install certain packages and missing rpm and stuff and fix things for me. thanks for helping.

thanks for helping. In a terminal window do:

Text mode console, or inside KDE?

sudo snapper list This gives a list of snapshots, with index number Now pick the snapshot from before your action, and do snapper rollback `that index`

There is also a YaST module. Documentation, there is a lot: https://en.opensuse.org/Portal:Snapper https://en.opensuse.org/openSUSE:Snapper_Tutorial https://doc.opensuse.org/documentation/leap/reference/html/book-reference/ch... 3 System recovery and snapshot management with Snapper # Abstract# Snapper allows creating and managing file system snapshots. File system snapshots allow keeping a copy of the state of a file system at a certain point of time. The standard setup of Snapper is designed to allow rolling back system changes. However, you can also use it to create on-disk backups of user data. As the basis for this functionality, Snapper uses the Btrfs file system or thinly-provisioned LVM volumes with an XFS or Ext4 file system. 3.1 Default setup 3.2 Using Snapper to undo changes 3.3 System rollback by booting from snapshots 3.4 Enabling Snapper in user home directories 3.5 Creating and modifying Snapper configurations 3.6 Manually creating and managing snapshots 3.7 Automatic snapshot clean-up 3.8 Showing exclusive disk space used by snapshots 3.9 Frequently asked questions -- Cheers / Saludos, Carlos E.

yes I understand, I have snapshots listed, so just to get this right, then the stuff I am remembering that grub2? also shows something about snapshots during boot, is something else? or maybe only on kernel level stuff or so? so still from inside the running, messed up 15.5 i rollback to that index I see listed, and immediately? comes into existence as a reverted situation, the icons, files, packages and all coming back instantly (kind of) or do I need to reboot aft that then or how does this work on a technical level? i am still often amazed that linux kind of can delete its own stuff while still running, so maybe it can revert, overwrite and reapply all this again while it is still running? thanks.

You have to reboot to actually be in the rolled-back snapshot.

i have successfully applied some earlier snapshot that made sense timestamp wise. the earlier is even from yesterday. unfortunately, the KDE start menu and most of the icons on the lower bar, are still vanished or greyish sheet. I had putty installed and that was for example pinned (favorited?) there. when i hover the mouse i kind identify its place but the putty icon is not there, also same for mozilla firefox. inside the konsole, i can start up firefox from command line. very odd. who or why have the elements of the kde menu been disabled or removed? i had thought such stuff was being stored inside a users /home/user/ directory ~ a mere removal of packages? also removes config files or where are these stored? how would I now know what else has been vanishing? do the snapshots not take place for users files e.g. in /home/ .... ? still thanks lot already, i now need to figure out how to restore the normal kde menu functionality or revert it back to default install time or vanilla time or something? or would i now go to booting the 15.5 iso and install it over/into this 15.5 still messed up a little bit? ty.

* cagsm [11-17-23 10:18]: you apparently did not use a snapshot dated prior to your install of calibre, where you caused your concerns or where your subsequent actions caused your concerns.

i dont understand. the only snapshot before that one i reverted back to, was back then from yesterday, and now the only snapshot being left is one from over ten days ago. yesterday and today only maybe three hours ago the kde was not affected at all etc. how can it be that reverting to a snapshot ten days ago. I just reverted back to ten days ago and the kde menu is still empty. there are some flaws in this system. this doesnt add up :((

yes everything is on one nvme disk and opensuse handled its partitioning. all default. kde desktop installation choice at the very beginning. kde menu seems to be not functioning, dunno why. how would i reinstall the kde? plasma? stuff to make it add default stuff. the system settings, the plasmadiscover the dolphin icons were not there at the bottom of the kde bar or screen. the whole kde start menu is empty. i have for example also a element-desktop from the opensuse download servers in the path devel languages nodejs 15.5 thats how I understand where this element-desktop (and element-web, and nodejs-electron package it is based on or compiiled to) comes from as well, and for example I can start the element-desktop manually from konsole, and even pin it to the disfunct apps area on the bottom of the screen, but when qutting element-desktop the element-desktop object pinned to that place, then turns out to be the wrapper or lower stack nodejs-electron itself, coming up emtpy and not loading the element-desktop/element-web objects or parts when simply clicking that pinned stuff. starting manually element-desktop works though. so there seem to be some config files? or config places folders etc missing for kde or plasma desktop to work properly?

Same disk yes, same partition no. Snapshots only apply to the single btrfs partition, not to /home which typically is on another partition. -- Cheers / Saludos, Carlos E. R. (from openSUSE 15.5 (Laicolasse))

You can also use "yast2 snapper". I posted links with documentation about everything you want to know. Start with the book, I would say. You can even print and bind it. After the command, you have to reboot to actually do it.

i am still often amazed that linux kind of can delete its own stuff while still running, so maybe it can revert, overwrite and reapply all this again while it is still running?

You are the master and commander. It just obeyed your orders.

thanks.

apparently I need to learn much more to handle repos and packages coming from them, but then again thats why i used the yast softwaremanagement module and not messing with rpm or so manually.

Snapshots have zero size the moment they are done. They are not photos of what was there. Just look for the one that YaST made before the operation. -- Cheers / Saludos, Carlos E. R. (from openSUSE 15.5 (Laicolasse))
