Additional context

My llvm is not 6.0 but 9.0. The error message after I performed step 4 is this:

++ sudo ldconfig
++ [[ -z /home/vbox/go ]]

• echo 'Install polycube'
  Install polycube
• cd /home/vbox/polycube-v0.9.0/scripts/..
• '[' '' == true ']'
• '[' '' == update ']'
• mkdir -p build
• cd build
• git log -1
  fatal: not a git repository (or any of the parent directories): .git
  ++ error_message
  ++ set +x

Then I tried methods from another issue: #322 and #328 and also the installation documentation
I performed;

1. cd polycube-v0.9.0/build
2. cmake ..
3. make -j $(getconf _NPROCESSORS_ONLN)
4. sudo make install
   After step 3 I had this error message:

installing polycubectl ...

• set -e
• echo 'installing polycubectl ...'
  ++ pwd
• pwdir=/home/vbox/polycube-v0.9.0/src/polycubectl
• mkdir -p /home/vbox/go/src/github.com/polycube-network/polycube/src/
• ln -f -s /home/vbox/polycube-v0.9.0/src/polycubectl /home/vbox/go/src/github.com/polycube-network/polycube/src/
• cd /home/vbox/go/src/github.com/polycube-network/polycube/src/polycubectl
• go get ./...

Maybe you should try the later or latest version, I tried the latest version it works fine.

can you tell me if you could install successfully in kernel version 5.15.0

在20.04安装使用脚本自动安装能成功，但是要解决很多问题，如果是在中国，要设置很多代理甚至更换镜像，即使开了VPN依然你看会连接超时，这个问题就慢慢解决吧，总能成功的，http代理,git代理，go代理等都要来一遍，最后就是一些环境错误，比如go command没有发现，很有可能是路径问题，即使go version能显示，但是在执行脚本的时候依然召找不到，解决方法：添加go路径
执行
sudo visudo
在文件末尾添加内容
Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin:/usr/local/go/bin"
Defaults env_keep += "PATH"
