Loading keyring from project library on Linux

[mafw]

I am trying to use the keyring package on Ubuntu 20.04 to get passwords stored in my keyring. Unfortunately the backend_secret_service$new()$is_available() function cannot find the secret service daemon on Linux if the keyring package is loaded from a local library within a project. This causes the package to default to using environmental variables and throws the following warning:

"Warning message:In default_backend_auto() :Selecting ‘env’ backend. Secrets are stored in environment variables"

This in turn means that I cannot access secrets stored in the GNOME keyring using the key_get() function.

I can solve this problem by loading the keyring package from the default user R library instead of the project library. I use the renv package to create the local library.

# Create project, activate renv and install keyring
library(usethis)
library(renv)
create_project(path = "MyNewProject", open = TRUE, rstudio = TRUE)

renv::activate()
renv::install("keyring")

# Load keyring using project library
library(keyring, lib.loc = "renv/library/R-4.0/x86_64-pc-linux-gnu-library")
backend_secret_service$new()$is_available()
#> [1] "FALSE"

# Install keyring in user library and load it from there
utils::install.packages("keyring", lib = "~/R/x86_64-pc-linux-gnu-library/4.0") 
library(keyring, lib.loc = "~/R/x86_64-pc-linux-gnu-library/4.0")
backend_secret_service$new()$is_available()
#> [1] "TRUE"

Keyring also finds secret service if I simply load it outside a project, which makes sense since the package is then loaded from the user library by default.

My first thought is that this has something to do with permissions on Linux? I use the keyring package on a Windows 10 machine without this problem.

One keyring install did not have the required system libraries available, this is why it does not support the secret service backend. Reinstall/recompile it with once you have the system libs.

OK this makes sense. When I reinstall the package I get the same error for the user package library. How do I check which libraries are missing? I am not getting any error saying I am missing libraries when installing the package and the keyring is working outside R.

Seems like you need libsecret-1-dev on Ubuntu.

My bad, there is a message when installing the package that on Ubuntu you should install libsecret-1-dev. I removed the keyring packaged, installed this library and then reinstalled keyring and now it works. Thanks and sorry about the confusion!
