Unable to load 'digest' package on a shiny server during application initialisation

I have a shiny application that I try to deploy on a shiny server. I am using the package golem.

I get this error in my browser :

An error has occurred

The application failed to start.

The application exited during initialization.

I get this error in the logs:

su: ignore --preserve-environment, it's mutually exclusive to --login.
Error in loadNamespace(name) : there is no package called ‘digest’
Calls: local ... tryCatch -> tryCatchList -> tryCatchOne -> <Anonymous>
Execution halted

I installed the package and can load it from my server console

I did check :

> .Library
[1] "/tmp/Rtmp0j1ghM/renv-system-library"


# and 

> .libPaths()
[1] "/var/www/others/formations_vne/shiny/vigie-analyse/renv/library/R-4.0/x86_64-pc-linux-gnu"
[2] "/tmp/Rtmp0j1ghM/renv-system-library"

and digest is in both :

If you run aplication in shiny server, they are run by shiny user which means that path to deafult libraries may also be different. To see what shiny user has access to, you can deploy simple app, that will write to text file output of

.libPaths()

and

rownames(installed.packages()).
