Well, crap. I felt brave and let 18.10 install over 18.04, and it apparently didn't go well.
I'm hitting a kernel panic at boot (error loading libargon2.so.0).
I'm fairly new to Ubuntu – is there a way to recover this – perhaps from a usb boot installation, without losing all of my current settings and applications?

I just solve it. I tried different solutions so maybe some steps are redundant or missing:
/mnt/f3kljjhfu23oghggnmnjyy
)Make mirrors for folders:
After this command you will be like root for old Ubuntu:
libargon2-0
for your OS from Debian packages repository (in my case file was named likelibargon2-0_0~20171227-0.1_amd64.deb
)./mnt/f3kljjhfu23oghggnmnjyy/tmp
)Install the downloaded deb file using the terminal from step #7 (so it will be installed to old Ubuntu):
