lightning community daemon – Command lnd not discovered even after putting in lnd

I attempted putting in lnd utilizing the instructions proven within the set up information.
I used these instructions:

git clone https://github.com/lightningnetwork/lnd
cd lnd
make set up

however after I strive working the lnd command, I get this:

Command 'lnd' not discovered

I’ve go1.18.1 put in. I did execute these instructions, however nothing modified:

export GOPATH=~/go
export PATH=$PATH:$GOPATH/bin

Listed below are the $GOPATH and $PATH variables:

echo $GOPATH 
/usr/native/go

echo $PATH
/house/ayoub/.native/bin:/usr/native/sbin:/usr/native/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/video games:/usr/native/video games:/snap/bin:/house/ayoub/.dotnet/instruments:/usr/native/go/bin:/usr/native/go/bin

How can I clear up this challenge?
I’m working Ubuntu 20.04.
