After repo sync yesterday (main branch / ToT), ~/trunk/src/scripts/update_chroot is now failing consistently with what appears to be a glibc version conflict.  I'm not exactly sure what the issue is though, several things look like issues, but none of them is actually that new in the codebase.

The error output says chromeos-base/chromeos-fonts requires sys-libs/glibc:2.2/2.2= .  Okay, that exact version requirement seems likely to fail...but again, how did that ever build recently?  Also, the ebuild file for chromeos-base/chromeos-fonts-0.0.1-r48 merely depends on sys-libs/glibc:= (no specific version).  Also, chromeos-base/chromeos-fonts-0.0.1-r49 is the current ebuild version, which I synced to, though it too merely depends on sys-libs/glibc:= (no specific version).

The error output also says virtual/libc requires sys-libs/glibc:2.2 .  This version-specific dependency is actually present in the ebuild, however it's been there for 8+ years.  That ebuild was updated last month in https://crrev.com/c/2940952 but that dependency was in the previous revision too, from 8 years ago.

Anyone have suggestions, or know of a recent change that might have caused this?

Yup, update_chroot is still failing with after syncing to main just now with the same error:

guess you haven't updated this thing in at least a year.  the conflicts are exploding out in a way we don't expect or normally see.

if you want to keep the SDK, you can prob force it forward with a manual upgrade or two like:
$ sudo emerge -GO `qlist -IC glibc zlib`

then see if upgrade_chroot is able to make progress.

Less than a year.  E.g. I'm pretty sure I had fully moved this checkout to `main` before this.  But yeah, I as infrequently as practical and tend to hop between checkouts to avoid syncing, mostly to avoid https://issuetracker.google.com/187794966 and avoid rebasing my local branches all the time.  (I really need to automate that aside from merge conflicts, or find automation that matches my workflow, or maybe adjust my workflow...)

Thanks!  That succeeded, and then afterwards update_chroot succeeded.  I haven't built/tested a full OS image with this checkout again yet, but so far so good.

What Linux distribution are you on, and what version? I know there is an issue with glibc on impish (Ubuntu 21.10) beta

The host distribution is a close derivative of Debian testing.

Mike is right that this issue is related to how long I waited between syncing + updating this SDK checkout.  I don't think there's any fundamental incompatibility with the host system, as I haven't run into this with other CrOS checkouts/chroots on the same machine.
