How to complete install of bitcoin-0.17.1 on linux (fedora 29) So I downloaded and unzipped bitcoin core. I now have bitcoin-0.17.1 sitting in my home directory . What next? How do I install and run this? (Obviously I am a newb, help much appreciated.)
After extraction files from the tar ball you have to install the contents of its bin subdirectory into the /usr/local/bin directory using the the install command. The install command is part of the GNU coreutils available on nearly every Linux distribution, and the /usr/local/bin directory is a standard location for self-installed executables (you may edit the commands below to use a different location).

If you use sudo to run commands as root, use the following command line:

sudo install -m 0755 -o root -g root -t /usr/local/bin bitcoin-0.14.2/bin/*


If you use su to run commands as root, use the following command line:

su -c 'install -m 0755 -o root -g root -t /usr/local/bin bitcoin-0.14.2/bin/*'


See reference here

You can then just run bitcoin-qt to startup the GUI
