so I was trying to set JAVA_HOME variable and some how I ended up facing this error every time I want to use terminal

Command 'poweroff' is available in the following places

* /sbin/poweroff

* /usr/sbin/poweroff

The command could not be located because '/sbin:/usr/sbin' is not included in the 

PATH environment variable.

This is most likely caused by the lack of administrative privileges associated with 

your user account.

poweroff: command not found

I can fix it with this command:

export PATH="/usr/bin:$PATH"

but every time I open new terminal I face the error again and I have to use this command again.

I would appreciate it if you could help.
by the way I use Ubuntu 22.04.1 LTS
