I have a laptop (Thinkpad L520) with 256 GB SSD drive with Ubuntu 17.04 on it (no other operating system installed). The drive is encrypted with means of Ubuntu installation medium. One day the system freezes and after boot send me to (initramfs) (see screenshot below). I also have a possibility to log in through live USB and see and decrypt the drive (with an error that operating system not found, but I still apparently can access the data).
I don't think that my SSD drive is corrupted, although I am ready to change my mind if some kind if diagnostic will be suggested to me. I think it was a problem with a system update, and that I haven't used to reboot my laptop too often. I have read on other topics that the kernel update might be the issue.
here is boot-repair summary (although I have been trying to 'fix' it using their operational procedure, am not sure I broke anything any more than it was): https://paste.ubuntu.com/24985651/
UPDATE:
UPD2: fsck -f /dev/sda5
fsck from util-linux 2.29
(initramfs)
Apropos SSD firmware diagnostic:
Here is the model and other data I was able to gather from Ubuntu. The manufacturer website send me to the software that is not supported by Linux, apparently. https://paste.ubuntu.com/25046170/
Gparted:
Gparted gives me the following error right from the start: The driver descriptor says the physical block size is 2048, but Linux says it is 512 bytes.
What I would like to do:
I would like to restore full functionality of my system, as I already have invested some time in configuration. Or I need to know how to find all of the files belong to me (in what folder to look) in order to reinstall the system. Thank you for your attention.

gpartedof your hard drive. It's not looking good right now. Have you checked your SSD firmware yet? – heynnema Jun 30 '17 at 20:57
