Title:
  Missing libgcc_s.so.1 decrypting partition on boot

Status in cryptsetup package in Ubuntu:
  New
Status in gcc-10 package in Ubuntu:
  New

Bug description:
  On focal with -proposed repo enabled. Updated all packages and
  rebooted. Upon entering the LUKS passphrase for disk decryption I get
  the following message, and cannot boot:

    "libgcc_s.so.1 must be installed for pthread_cancel to work"

  Booting with the previous kernel works.

  Found this question with an identical issue:
  https://askubuntu.com/questions/1190687/ubuntu-19-10-missing-lib-gcc-
  so-1-after-kernel-update, which points to "/usr/share/initramfs-
  tools/hooks/cryptroot" being unable to find that lib. It was looking
  in "/lib/x86_64-linux-gnu/", but libgcc_s.so.1 is not there, but at
  "/usr/lib/" and "/usr/lib/x86_64-linux-gnu/". Temporarily fixed by
  copying the file to "/lib/x86_64-linux-gnu/" and regenerating the
  initramdisk.
