I try to install the lastest version of R on my Ubuntu 22.04.3. For that I need to run first sudo apt-get update but in the output I have Signed-By conflict issues :

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

I try to remove it :

sudo rm /etc/apt/trusted.gpg.d/marutter_pubkey.gpg

but it couldn't be removed

rm: cannot remove '/etc/apt/trusted.gpg.d/marutter_pubkey.gpg': No such file or directory

cat /etc/apt/sources.list.d/r-project.list


deb [signed-by=/usr/share/keyrings/r-project.gpg] https://cloud.r-project.org/bin/linux/ubuntu jammy-cran40/


deb [signed-by=/usr/share/keyrings/r-project.gpg] https://cloud.r-project.org/bin/linux/ubuntu jammy-cran40/

is the ppa:marutter/rrutter4.0 installed?

sudo apt list --installed | grep marutter/rrutter4.0

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

  • Show the output of your sources file where you added the R repositories? – Thomas Ward Nov 27 '23 at 21:43
  • Do you also have the PPA ppa:marutter/rrutter4.0 installed? Michael Rutter maintains a different PPA for R. – user68186 Nov 27 '23 at 22:04
  • i don't, I'm gonna try to install it now – Luna Saunier Nov 27 '23 at 22:08
  • well actually, I'm not sure if it's install or not. The thing is that I already try to follow many other forums command line before asking here, so I know that I did installit at some point but I though that I removed it. I let my output on my script – Luna Saunier Nov 27 '23 at 22:19
