I was having problems updating a chroot named sid, this is how I fixed it.

Run sudo crouton -u -n sid to update the chroot normally until CRAS compile fails
Run sudo chmod +w /usr/local/chroots/sid/prepare.sh
Run sudo vi /usr/local/chroots/sid/prepare.sh to edit the setup script
Apply this patch manually:

That is, go to line ~498ish and add the s/-Werror//g line as shown above, without the plus sign.

Type:wq<enter> to save and exit
Run sudo chmod -w /usr/local/chroots/sid/prepare.sh to prevent crouton from thinking it’s “invalid”
Run sudo enter-chroot -n sid
Answer Y to run the setup script. There will be compile warnings still, but the build should succeed, and the update should continue as normal.

However, you will need to reapply this fix every time you update. If you want a longer-lasting solution, you’ll need to extract crouton’s scripts. I haven’t tried it, but here’s a tutorial: https://github.com/dnschneid/crouton/issues/4450#issuecomment-870781102.
