Linux installation instructions

Standard installation script:
/bin/bash -c "$(curl -fsSL https://www.sdrplay.com/software/install.sh)"

Silent install and accept license agreement:
/bin/bash -c "ACCEPTLICENSE=1 $(curl -fsSL https://www.sdrplay.com/software/install.sh)"

Install on non-Ubuntu LTS releases (do not check for dependencies):
/bin/bash -c "NOTSUPPORTED=1 $(curl -fsSL https://www.sdrplay.com/software/install.sh)"

Install from downloaded files instead of getting the files from the server:
/bin/bash -c "DONOTDOWNLOAD=1 $(curl -fsSL https://www.sdrplay.com/software/install.sh)"

Here are the files you will need to download for the offline install, choose your architecture and download ALL 4 files – after downloading the files you need to run the install script from a terminal window from the same folder that the files have been downloaded to:
