Hello, I have tried to upgrade R to 4.0. I have added `deb http://cloud.r-project.org/bin/linux/debian buster-cran40/` to `/etc/apt/sources.list` (but I removed cran35). Btu when I run `apt-get update; apt-get install r-base r-base-dev` I get an error. I think it depends on r-base-core, since it depends on these obsolete libraries: ``` $ sudo apt-get install r-base-core Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation:
The following packages have unmet dependencies: r-base-core : Depends: libc6 (>= 2.27) but 2.24-11+deb9u4 is to be installed Depends: libcurl4 (>= 7.28.0) but it is not installable Depends: libgfortran5 (>= 8) but it is not installable Depends: libicu63 (>= 63.1-1~) but it is not installable Depends: libpcre2-8-0 (>= 10.32) but it is not going to be installed Recommends: r-recommended but it is not going to be installed Recommends: r-base-dev but it is not going to be installed Recommends: r-doc-html but it is not going to be installed E: Unable to correct problems, you have held broken packages. ``` How can I upgrade these libraries on Chromebook?
