Note: dbplyr version 2.0.0 is installed. In my computer unitizer version 1.4.11 is installed. install.packages() fails with unitizer version 1.4.12

Can you try to install dbplyr manually and post the error message you get?

Should I uninstall dbplyr 2.0.0 first?

If it is installed on a different library path, yes, otherwise, is up to you, I'm more interested in the additional information that the error message can provide.

That is weird, it installs without issues, can you try restarting your R session and trying to install unitizer again?

Yesterday I was sanctioned (flagged) by the community and they treated my messages as spam without any explanation just because something named AKISMET considered it so.
Today, despite my disqualification, I downloaded version 1.4.12 from: https://packages.debian.org/bullseye/all/r-cran-unitizer/download and installed it on my computer with gdebi.
In the attached graphic you can see the RStudio PACKAGES section and see the two packages installed, but when I tell RStudio or R in the command console to install unitizer 1.4.12, it tells me that there are errors and that it cannot install it .
Is my message spam?

To avoid autoflaging of your posts, post console output as formatted code, here is how to do it

About your issue, I'm afraid you are not providing any relevant information, please post the actual error message you get (as formatted code), also, why do you have both versions installed? Make sure to uninstall any previous version from your other library paths (you can get them by running .libPaths()).

**Initial steps:**

1) Uninstall unitizer, command console, call as root user
2) R reports that unitizer is not installed
3) The list of installed packages is requested and with grep the names that contain unitizer are obtained
4) The list of installed packages reports two instances where the unitizer is shown as installed
5) Image that summarizes the above

**Steps with RStudio**

1) Attempting to uninstall unitizer
2) The list of installed packages is built
3) From the above list, it is checked with grep if unitizer is installed
4) Like the call to R from the command console, unitizer appears as installed
5) See the following image of RStudio that shows on the right how unitizer is not installed, and on the left the output of the RStudio Console

**Reinstalling unitizer from command console called as normal user:**
