Version 0.1.0-1 of rust-serde-ignored is marked for autoremoval from testing on Thu 30 Jun 2022. It depends (transitively) on nvidia-graphics-drivers-tesla-470, affected by #1011146. You should try to prevent the removal by fixing these RC bugs.
Migration status for rust-serde-ignored (0.1.0-1 to 0.1.2-1): Waiting for test results or another package, or too young (no action required now - check later)
