No plank after 21.04 upgrade

after upgrade my os to 21.04, I don’t see the plank. please is it normal ?

No. That’s not normal.

Do check to see if you have both plank and the ubuntu budgie meta package installed.


sudo apt install ubuntu-budgie-desktop budgie-desktop-environment plank

I suspect you may have accidently removed one of the meta packages and the upgrade assumed you didn’t need packages such as plank anymore.
