Dear Maintainer, I tried to have a look and it looks like being related to the libgrpc++1 package.
The _ZN4grpc13ClientContextC1Ev symbol was included in libgrpc++1 versions up to 1.17.2-1. Since version 1.22.0-2 it is missing from that library. Because 1.26.0-2 is the first version after 1.16.1-1, which got uploaded to unstable (other versions just in experimental), this issue got visible since 2020-03-21. A local rebuild of sysdig against libgrpc++1 1.26.0-2 seems to work. Therefore it looks like there was an ABI change in libgrpc++1. I am not sure what actions on grpc side are needed, but at least a rebuild of sysdig seems necessary. Kind regards, Bernhard
