the following error is coming when trying to upgrade .

hi everyone ,


during the updating the error shown in screenshot is occurringAttachment 244095 ,,can anyone help to fix it ?

That error usually means that you have another package manager (synaptic or Software Center) open at the same time - if so close it - if not then some previous package management operation didn't exit cleanly and left a 'stale lock' which you may need to remove manually

hello ,steeldriver

how i can do it manually ?

To remove the lock manually copy and paste this command in a terminal.

Code:

---

sudo rm /var/lib/apt/lists/lock

---
