E: Unable to locate package bpfcc-tools


You check your os version by this command:

cat /etc/os-release

VERSION="16.04.6 LTS (Xenial Xerus)"
PRETTY_NAME="Ubuntu 16.04.6 LTS"

Solution: Upgrade your system version

Upgrade your ubuntu system version to 18+:

cat /etc/os-release

VERSION="18.04.4 LTS (Bionic Beaver)"
PRETTY_NAME="Ubuntu 18.04.4 LTS"

Test Again

Then you can test your vim again:

apt install build-essential git make libelf-dev clang strace tar bpfcc-tools linux-headers-$(uname -r) gcc-multilib

Note on Kernel version: make sure to have a recent kernel to run the ebpf examples, a kernel version >=5.0.0 will do the job. Most Ubuntu 18.04 providers are shipping with the kernel 4.15 that doesn’t work for most of the examples. Upgrading options are left to the reader, we’ve been successful on aws by installing the linux-image-5.0.0-1019-aws package.

According to wikipedia of ebpf:

Since version 3.18, the Linux kernel includes an extended BPF virtual machine with ten 64-bit registers, termed extended BPF (eBPF). It can be used for non-networking purposes, such as for attaching eBPF programs to various tracepoints.[4][5][6] Since kernel version 3.19, eBPF filters can be attached to sockets,[7][8] and, since kernel version 4.1, to traffic control classifiers for the ingress and egress networking data path.[9][10] The original and obsolete version has been retroactively renamed to classic BPF (cBPF). Nowadays, the Linux kernel runs eBPF only and loaded cBPF bytecode is transparently translated into an eBPF representation in the kernel before program execution.[11] All bytecode is verified before running to prevent denial-of-service attacks. Until Linux 5.3, the verifier prohibited the use of loops.
