Tree is a recursive directory listing command that produces a depth indented listing of files, which is colorized ala dircolors if the LS_COLORS environment variable is set and output is to tty. Tree has been ported and reported to work under the following operating systems: Linux, FreeBSD, OS X, Solaris, HP/UX, Cygwin, HP Nonstop and OS/2.
Note that if you just removed tree from APT distribution you will have to run the following command to regenerate GNU Bash's command search hash so that it will fall back to the command provided by the snap:
simply logout and re-login the user session will work.
