Getting “The input is not of cabinet format” on Discover

np flag

Discover lists 2 items to update:

"Dell System Firmware"

"UEFI dbx"

I don't know how to search for this on the cli. But if I try to install directly in Discover, I get 2 errors “The input is not of cabinet format”.

How can I fix this?

Ubuntu 22.04.1 LTS KDE Frameworks Version 5.92.0

Done. Thanks. Seems Discover is getting its packages some where else.

To solve the issue you can update the firmware manually:

  1. Verify you have fwupdmgr installed
sudo apt install fwupd
  1. Look for firmware updates
sudo fwupdmgr refresh
  1. Update
sudo fwupdmgr update
  1. Reboot to apply changes

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
