I installed lnd (lighgning network daemon) using the below command.
sudo install -m 0755 -o root -g root -t /usr/local/bin lnd-linux-armv7-v0.5.1-beta/*
What's the cleanest way to remove/rollback this? (I'd like to install a different version). I was thinking of simply removing the binary but would that be enough?
rm /usr/local/bin/lnd
I downloaded the tar.gz from the tutorial I assume you used and there are only two files there lnd and lncli.
Simply delete these with sudo rm -f /usr/bin/lnd /usr/bin/lncli.
install copies the files specified on the command line (in your case, all files inside lnd-linux-armv7-v0.5.1-beta to the target directory (in your case, /usr/local/bin). In order to undo this, you must find you which files you had in lnd-linux-armv7-v0.5.1-beta, and remove files with identical names in the target directory.
If the file names didn't change across two releases, simply installing a newer version in the same directory is enough. install overwrites existing files during installation.
