Unable to locate libssh2 package
and I tried installing libssh2-1 package using the following command
sudo apt install libssh2–1-dev libssh2–1
and I got an error message
E: Unable to locate package libssh2–1-dev E: Unable to locate package libssh2–1
Now it is my understanding that these packages are part of default Ubuntu installation so why are these packages missing? What should I do? I already tried apt update command but it doesn't help.
