Hi RMs,

There's a long awaited transition of Protobuf. It clashes with the
ruby3.1-default transition, but as I know its rebuilds are just
starting[1].
On the other hand I'm done with the rebuilds and patched all issues,
this transition may start immediately at your decision. The only
downside is that the Sid version of cura-engine is FTBFS and to fix
it, the libarcus transition (only affecting this package) will need to
be done.

Failing packages and fixes in detail.
Level 2:
android-platform-frameworks-base has my patch already applied [2] for
experimental (not Sid!).
libarcus builds in Sid, but not the version in experimental for which
I provided a fix [3].
target-factory changed library symbols [4], maintainer will need to update that.

Level 3:
cura-engine fails with the Sid version [5], with the libarcus
transition done it compiles fine.
grpc-java for which I provided the fix [6], the maintainer noted he
will be ready to update the package.
llvm-toolchain-13 for which I provided the fix [7], other problems
seem to be fixed with the upload just happened.
llvm-toolchain-14 for which I also provided the fix [8], its other
problem [9] might be wrongly closed by cross referenced
llvm-toolchain-15 package - but Sylvestre Ledru seems to be aware of
issues anyway.

Thanks for considering,
Laszlo/GCS
