I get the below errors when I hit sudo apt upgrade. I am unable to fix the error. Any help, please?

Seeing the same problem here after `sudo apt upgrade`. Noticed four packages which were being held back the other day, now they installed and broke dpkg. Tried the solutions outlined [here](https://bugs.launchpad.net/ubuntu/+source/dpkg/+bug/1871963/comments/13) for Focal, but no luck.

The problem is that I cannot install new packages because of this issue.

I tried https://askubuntu.com/a/1407132/560505 removing the packages and it works. You should check first if you have secure boot enabled.

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.
