Error in updating

hey i am getting error in updating brave browser whenever i try it show this

How shall i resolve it

The message states that Brave is in use or it is using other processes in the background. Was Brave in use during the update? If not, try a reboot and run the update again. If you get the same error again, open a terminal wirh Ctrl+ Alt+ T and enter (based on your screenshot):

kill 1893 2011 ...

When you have entered all the PID numbers, press enter. If you are asked for confirmation, enter


then press enter.

Then run the update again.

ya you are right many extensions were working in background but i was unable to kill from terminal so i kill it via stacer
