Singularity support broken

[louisaslett]

The Singularity support discussed in #277 and documented at https://www.rocker-project.org/use/singularity/ seems to no longer work with the latest image, because the pam-helper seems to have been dropped.

I get the following:

$ PASSWORD=mypass singularity exec rstudio.simg \
>     rserver --www-port 8080 --auth-none=0 --auth-pam-helper-path=pam-helper
INFO:    Convert SIF file to sandbox...
12 May 2020 16:55:23 [rserver] ERROR PAM helper binary does not exist at /usr/lib/rstudio-server/bin/pam-helper; LOGGED FROM: bool rstudio::server::pam_auth::pamLogin(const string&, const string&) /var/lib/jenkins/workspace/IDE/open-source-pipeline/v1.2-patch/src/cpp/server/ServerPAMAuth.cpp:445

The error line appears once I type in a username and password to log in.

This did not happen with an image I pulled just 4 days ago.

Thanks -- that had already been reported a few days ago @cboettig just addressed and closed it but possibly over in ../rocker-ver.

Sorry, could you expand which image to use? I see this issue with the latest image:

singularity pull --name rstudio.simg docker://rocker/rstudio:latest

[cboettig]

I see:

singularity pull --name rstudio.simg docker://rocker/rstudio:latest  && PASSWORD=mypass singularity exec rstudio.simg rserver --www-port 8080 --auth-none=0 --auth-pam-helper-path=pam-helper
