failed:
1.D-Bus Connection Failure: Logs show errors like [145:172:0701/132304.784844:ERROR:dbus/bus.cc:408] Failed to connect to the bus: Could not parse server address: Unknown address type, indicating D-Bus configuration issues, possibly due to the container environment not fully supporting system services.
2.ptrace Unimplemented: Errors like [0701/132312.401705:ERROR:third_party/crashpad/crashpad/util/linux/scoped_ptrace_attach.cc:27] ptrace: Function not implemented (38) suggest that ptrace, required for Chromium’s crash reporting, is unavailable, likely due to QEMU or kernel restrictions.
3.QEMU TCG Assertion Failure: The error ERROR:../../accel/tcg/cpu-exec.c:928:cpu_exec: assertion failed: (cpu == current_cpu) indicates a failure in QEMU’s translation cache generator (TCG), common when emulating x86_64 on ARM64, as seen in the logs with "Bail out!" messages.
