I installed some software like Docker, Jenkins etc on my PC but it's not working, all it's showing is that Docker-Desktop depends on qemu-system-86

I've being trying to install it but this is what I've been getting as response

I believe those are the important lines in your output. The qemu-system-x86 package may have gotten corrupted during download. First clear the apt cache:

sudo apt-get clean

Then update the package list and try to finish any pending installs:

sudo apt-get update
sudo apt-get -f install
sudo dpkg --configure -a

Your output says Package qemu-system-x86 is not installed, so i don't think there is any need to remove/purge qemu-system-x86.

If the above commands are successful, then try to install qemu-system-x86 again. If those commands give you errors, please post them here.

Once everything else is fixed, you can run sudo apt autoremove to remove unneeded packages.
