** Description changed:

  debootstrap currently hardcodes SHA_SIZE to 256 in
  ./debootstrap/debootstrap which fails with the new SHA512 only stonking
  index files.
  
- I assume this also affects livecd-rootfs and causes the recent image
- build failures.
+ This is also affecting livecd-rootfs builds of stonking (one buildlog
+ example:
+ 
https://launchpadlibrarian.net/868008144/buildlog_ubuntu_stonking_amd64_edubuntu_BUILDING.txt.gz)
  
  The fix here would be to first check if SHA512 is available and then
  falling back to SHA256 (we must prefer sha512 over sha256 since the by-
  hash/ folders are only guaranteed to exist for the strongest hash in the
  Release file).
  
  ```
