Install protobuf 3.5 on Ubuntu 18.04

# Make sure you grab the latest version
curl -OL https://github.com/google/protobuf/releases/download/v3.5.1/protoc-3.5.1-linux-x86_64.zip

# Unzip
unzip protoc-3.5.1-linux-x86_64.zip -d protoc3

# Move protoc to /usr/local/bin/
sudo mv protoc3/bin/* /usr/local/bin/

# Move protoc3/include to /usr/local/include/
sudo mv protoc3/include/* /usr/local/include/

# Optional: change owner
sudo chown $USER /usr/local/bin/protoc
sudo chown -R $USER /usr/local/include/google

you might need to install a dep too:

sudo apt-get install libatomic1

I was able to get what I needed with sudo apt-get install libprotobuf-dev protobuf-compiler

@cboulay apt install gets 3.0

I'm using Ubuntu 18.04, install protoc using this, and when I tried to compile my .proto file it said

protoc-gen-go: program not found or is not executable
--go_out: protoc-gen-go: Plugin failed with status code 1.

while run protoc-gen-go tell me

zsh: command not found: protoc-gen-go

Any idea how to make it works? Thanks

same problem

Install protoc-gen-go using:

sudo apt install libprotobuf-dev protobuf-compiler golang-goprotobuf-dev -y
