On Lubuntu 18.04, I open pcmanfm
$ pcmanfm .
and after looking at the thumbnails of the image files under the current directory in pcmanfm, I closed the window of pcmanfm by Alt-F4, but it is still hanging on the foreground in the terminal emulator.
I move it to background by Ctrl-Z and bg 2, and kill it, but doesn't work.
$ jobs -l
[2]+ 31124 Running pcmanfm . &
$ kill %2
$ jobs -l
[2]+ 31124 Running pcmanfm . &
$ sudo kill 31124
$ jobs -l
[2]+ 31124 Running pcmanfm . &
Its state is Sl, S means "interruptible sleep (waiting for an event to complete)" and l means "is multi-threaded (using CLONE_THREAD, like NPTL pthreads do)". So I wonder why I can't kill the process? How would you kill it? Thanks.
$ ps aux | grep [3]1124
t 31124 0.8 0.7 693952 57064 pts/9 Sl 06:34 0:47 pcmanfm

You don't needsudo.sudois not your friend. When you can't cut the bread, because it is in the bread box, don't use a chain-saw, instead take it out of the box.

If the process is started by you, then you have permission to kill it. If bread is in bread-box (a place to store bread (not often used with today's modern bread substitute)), then you can not cut it with knife.

On a vanilla Lubuntu 18.04, I seepcmanfm --desktop --profile lubuntuwithSland this is without actually launching pcmanfm. Don't you see something like that immediately after you log in?

By default kill only sends a TERM signal, for some reason pcmanfm is ignoring this signal. If you pass option -KILL to kill, then it will send the signal to the scheduler, and the process will be removed with no chance to clear-up, or appeal.
You do not need extra privileges (sudo), to kill processes that you own. sudo can be dangerous, don't just use out of frustration.
