Problem

On a fresh installation of Posit Package Manager, you may see an error similar to the following:

Error running services: Error: Unable to run an executable program within the Server.TempDir='/tmp'; this directory may be mounted 'noexec': Unable to run validator /tmp/tempdir-validator-xxxxx: fork/exec /tmp/tempdir-validator-xxxxx: permission denied;

This error usually occurs when the /tmp directory is mounted as noexec.

Solution

First, you could start by remounting the tmp directory with the following command:

sudo mount -o remount,exec /tmp

From there, restart Package Manager so that it can see these changes:

sudo systemctl restart rstudio-pm

Alternative Solution

Failing the above, you will need to adjust the TMP directory that Package Manager uses:

https://docs.posit.co/rspm/admin/process-management/#temp-directory

For example, with this addition below to your /etc/rstudio-pm/rstudio-pm.gcfg configuration file in the [Server] section:

; /etc/rstudio-pm/rstudio-pm.gcfg
[Server]
TempDir = /package-manager-tmp/

Package Manager will now use this directory below instead of /tmp:

TempDir = /package-manager-tmp/

With that change, you'll also need to make the directory specified and allow access:

mkdir /package-manager-tmp/

chmod 1777 /package-manager-tmp/

Once complete, a restart of the Package Manager service is required so that it can see these changes:

sudo systemctl restart rstudio-pm
