Bioconductor version 3.14 (BiocManager 1.30.16), R 4.1.3 (2022-03-10) Warning message: package(s) not installed when version(s) same as current; use force = TRUE to re-install: 'AnnotationDbi'

Why does this happen? Did I do something wrong?

If there is not a newer version of the package, doing an install of the package will produce this warning which means it is already installed and there is not a newer version that needs to be installed. You can proceed with library('AnnotationDbi') and use the package as normal.
