"Conflicting values set for option Signed-By regarding source" error after installed r-project

kw flag

yesterday I installed r-project on Ubuntu 22.04 and then I got the problems. The problem is that when I run sudo apt-get "function" on the terminal where "function" stands for update, upgrade, autoremove etc, it is returning errors.

For example:

polimer@polimer-ideacentre-A340-22ICK:~$ sudo apt update

E: Conflicting values set for option Signed-By regarding source https://cloud.r-project.org/bin/linux/ubuntu/ jammy-cran40/: /usr/share/keyrings/cran.gpg != /usr/share/keyrings/r-project.gpg
E: The list of sources could not be read.

So, I'm unable to run the commands on my system. Please help me out.

And thanks in advance for attention.

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.
