What does ... dpkg -l "linux*" ... on a nice wide screen show you?

The utrace-patched kernel PPA appears to be missing its matching
kernel-dbgsym, now on a closer look.  This means that while user-space
probes work, some kernel.* won't (will be skipped due to build-id
mismatches).

One may need to replicate the PPA work and generate a ddeb locally.
