Two steps: sudo curl -fsSL https://cloud.r-project.org/bin/linux/ubuntu/marutter_pubkey.asc | gpg --dearmor | sudo tee /etc/apt/keyrings/cran.gpg > /dev/null
This downloads the key, turns it in to a binary in the correct format, then writes the key in the keyring. Then I edited my R .sources file ( in directory: /etc/apt/sources.list.d) and pasted in the following in the Signed By: field. /etc/apt/keyrings/cran.gpg So now my R .sources file looks like this: Types: deb URIs: https://cloud.r-project.org/bin/linux/ubuntu/ Suites: noble-cran40/ Components: Signed-By: /etc/apt/keyrings/cran.gpg then sudo apt update and the Missing Signed-By notice is gone. Now just have to wait for Michael to give us R 4.5.1! And I didn't even need to make a cup of coffee! Will do that now... Thanks Dirk and everyone for making R available on Linux, and specifically Ubuntu. Cheers, Simone.

Also, I should probably RTFM. 😄 There are two distinct issues here, and you are conflating them. Treating them separately makes it easier. One is that indeed as of right now we have no R 4.5.1 for Ubuntu at CRAN. Michael will get to it, he always has. (I did my part on the Debian bits he uses, now we wait.) You can use rocker/r-base aka r-base with 4.5.1 now, as you can for Debian unstable/testing. Two is that apt input format changed from .list to .sources, and also changes how security keys are reported / required -- all following some time after 22.04. I think that hit me for 24.04 but my repos (i.e. r2u) do the right thing now, as do the machines I run. How to set that up on your end is more of a generic Ubuntu question you could google (and sorry I do this to you but I don't have a link handy as I said it is coming up to 23h on a Sunday here). My scripts (for r2u, for r-ci, ... ) do the right thing, you can find it there too. I have no issue either on this machine (still 24.10 nor on another updated to 25.04). I am sure you can sort this out over one fresh hot cup of coffee or tea. If and when you do feel would you mind sending the notes to this thread?
