Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. Troubleshooting is needed to identify the symptoms. Determining the most likely cause allows to eliminate the potential causes of a problem.

Command line notation

Throughout the documentation, we’ll show some commands used in the terminal. Lines that you should enter in a terminal all start with $. You don’t need to type in the $ character, it indicates the start of each command. Lines that don’t start with $ typically show the output of the previous command.

The typical command line interface looks like this. There two separated commands, so you should enter it one by one.

$ wget
$ sudo apt install ./eosio_1.7.0-1-ubuntu-18.04_amd64.deb

If you see && \ symbols at the end of the first command, it means to copy all lines and paste as one command.

$ wget && \
      sudo apt install ./eosio_1.7.0-1-ubuntu-18.04_amd64.deb
