Latest updates on SLED 15 SP1

Hello again. Turning on my laptop after a week’s absence, I found it impossible to install the latest updates, including that of Firefox. Moreover, after rebooting, my system refused to continue beyond the login screen, so I had to use an earlier snapshot. Is this a personal mess, or it has occured to anyone else as well? Thanks for your time.
