I am waiting for an hour.
It may have installed it. I have seen it install correctly, but the button doesn’t change. Try to exit Atom, reopen it and see if it is installed.
It did not help.
I’m assuming that it is the
remote-ftp package in that screenshot you want to install but can’t?
If restarting Atom doesn’t do anything, can you try running
apm install remote-ftp from the command line? Once that command is finished, restart Atom, and see if the package is installed. If the command shows any errors post them here.
