[R-sig-Debian] Updating to R 4.5.1 on Ubuntu Plucky

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?

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.
