Failed to update and now cannot boot, showing initramfs
When i just installed my LM 18.2, in the Update Manager for some very personal reasons i've chosen not the 1st quickest local mirrors, but 2nd and 3rd instead. Everything was nice until few days later my Update Manager started showing ominous red icon in the tray: it suggested i would rather choose the quickest local mirrors. Being possessed with naturally daring behavior, i've tried to choose some very different mirrors, refreshed list of updates and tried to install them. After some errors i've switched to 1st quickest local mirrors, refresh cache, refresh list of updates, tried to install them, but then Update Manager again responds with error message. 'Okay, things will sort themselves out', - i thought and turned the machine off.
Next day, when i tried to boot the system, instead of LM 18.2 Cinnamon x64 i saw something that which i intuitively figured out as BusyBox with initramfs going on.
It stated about line 24 not being found in some script.
Somehow, i feel that this line or this script should be fixed, but i had little success trying initramfs. Gave up when tried to 'pwd' (print working directory) and system said i'm working within '/', which is root, probably. I have little wish to mess up root.
Here's my machine info from last attempt to do recovery:

Would appreciate any kind of help. I promise not to do any daring behavior until i finished my 9000 hours of GNU/Linux education.
