That looks like an RStudio message.? Do you get it if you run
install.packages() in command line R?

Hello,
R 4.0.0 on Ubuntu 20.04, sessionInfo() below.
Since I updated to R 4.0 that every time I try to install a package with
install.packages() the warning in the title shows up at the end, be the
installation successful or not. If it is successful, the package loads
with no problems, so I'm not very worried but it isn't normal (expected)
behavior, is it?
Here is a run of install.packages().
install.packages('cowplot')

Also, I'm running this on RStudio and haven't changed the R library
