If you cannot install any packages **and** have an error message saying your home directory is not writeable or the directory is not correctly mounted then you should raise a call in [Service Now](https://nhsnss.service-now.com/phs/) and ask to have your cache cleared. Only raise a service call if you are getting these error messages.

#### How do I install the `{curl}` package?

The `{curl}` package from v6.0.0 onwards requires a C++17 compiler which the existing Posit Workbench environment does not provide. The solution is to install v5.2.3 of the `{curl}` package:

```{r}
# Install {curl} v5.2.3 from the last Posit Package Manager snapshot that contained this version
install.packages("curl", repos = "https://ppm.publichealthscotland.org/all-r/__linux__/centos7/2024-11-04+Y3JhbiwzOjIyNzUsNDoyMjQ5LDU6MjM4OCw2Ojg2Myw3OjIzNjksODoyMzE0OzI4MkU4MzFE")

remotes::install_version('curl', '5.2.3')

This is the suggested way to install (https://ppm.publichealthscotland.org/client/#/repos/3/packages/curl)

This bit isn't needed, since we're already assuming people have access to PPM in the above example, and that will serve binary or source as available.

```

#### How do I install the `{hablar}` package?

The `{hablar}` package cannot be installed as a pre-compiled binary; attempting this gives an error. Therefore, you need to force R to install the source version by specifying the URL for the source version of packages on Package Manager. However, `{hablar}`'s dependencies can be installed as binaries first.
