Same result here with that OS version

This preview targets 18.04. We're planning on having more version/distros enabled with 1.0. There should be nothing preventing it from running on 20.04 (since BPF is enabled) but you may have to build it using a later version of BCC than what our build instructions are using today.

same here. doesn't work on 20.04 (20.04 is the current LTS!!)

You need to build against a v0.12.0 version of BCC:

Note that this version of BCC seems to ship with 20.04, so it does not need to be separately compiled.

Bumping BCC to 0.12.0 might be enough for Ubuntu, but not for the rest of the world, as 0.14.0+ is needed to be able to be built with the current version of clang. Doesn't really make sense to update to a slightly less old version that's still broken 🙃

That may be true, but this issue is specifically about getting it to work on Ubuntu 20.04 LTS

Thanks, @mletterle!

Note that this version of BCC seems to ship with 20.04, so it does not need to be separately compiled.

Do you know if that includes the statically linked library, libbcc.a? The reason we are building it with procmon for now, is that we statically link libbcc.a and last we checked they don't include the .a library in their packages. We do this in order to have a "hot drop"-able binary that can be theoretically used on any platform with the necessary kernel version/config with no additional installations. The obvious limitation to all this is when kernel headers don't match up (usually due to version mismatches), the BPF programs will fail to compile at runtime despite procmon itself running just fine.

Ah no, it doesn't appear to include the static version

same problem with you

This preview targets 18.04. We're planning on having more version/distros enabled with 1.0. There should be nothing preventing it from running on 20.04 (since BPF is enabled) but you may have to build it using a later version of BCC than what our build instructions are using today.

I tried the same on 18.04, it does not produce any error, procmon UI opens but nothing is displayed.
