version `GLIBC_2.27' not found (required by pacman) - broken pacman

Hi everyone! Today I was gonna update my system after a month hiatus due to lack of system space. During my first tentative I ran into this problem:

error: failed to prepare transaction (could not satisfy dependencies)
:: ffmpeg2.8: installing x265 (2.8-1) breaks dependency 'libx265.so=151-64'

And came upon this forum post, so I upgraded pacman alone. Next, pacman was unable to run anymore because of the aforementioned glibc version conflict:

pacman: /usr/lib/libc.so.6: version `GLIBC_2.27' not found (required by pacman)

Since pacman is unable to run, I'm unable to downgrade it or upgrade glibc alone. --ignore glibc does not help. Do you have any idea of how can I unscrew what I just screwed?

Somehow you missed many relevant recent threads on the exact problem you had and instead used something from 6 years ago that was most likely horrible advice even at the time.

Do you have your previous version of pacman in your cache?  If so, you could manually extract it.  Otherwise, you could use a live iso with a functional pacman to properly update your system.
