title: Unable to open '/boot/vmlinuz-5.x.x.x-generic.dpkg-new': Operation not permitted [Need solution without removing antivirus from system]
body: <p>In the last couple of days, I have gone through some unmet dependencies issues while upgrading. I tried to install those packages separately but couldn't come up with a solution.</p>
  <p><strong>I know one solution that is to remove the antivirus from the system. But I'm not permitted for me to remove the antivirus. I want another solution without removing anti-virus from the system.</strong></p>
  <p>It shows while unpacking the package:</p>

  <p>It's annoying and I cannot install any other packages.
  Any suggestions on how can I fix that?</p>
