I have a Bq10 tablet running Ubuntu-touch OTA-11. I want to be able to work with Ruby and rails apps.

Usually I use rvm for this.

Is it possible to install rvm [or something similiar] using ubuntu-touch and the libertine containers?

So far I have had lots of trouble installing rails via rvm. The typical command is \curl -sSL https://get.rvm.io | bash -s stable --rails

I have tried lots of variations of installing it with libertine-container-manager but none have been successful.

If I enter the container I get the following error:

root@ubuntu-phablet:/# \curl -sSL https://get.rvm.io | bash -s stable --rails Downloading https://github.com/rvm/rvm/archive/1.27.0.tar.gz Downloading https://github.com/rvm/rvm/releases/download/1.27.0/1.27.0.tar.gz.asc gpg: fatal: can't create directory/home/phablet/.gnupg': No such file or directory`

What does work is to add a new user within the container and then issue the normal commands. Within the container this will allow me to install ruby and rails with rvm but I can't access any rvm commands from outside the container.

Is there a possible solution to this?

Note I guess this question might be generalised to more than just rvm, it could be about installing software with git, or issuing commands which pipe text into bash ...

I don't get the error you're getting. I see rvm download a slew of arbitrary shell script commands from site on the internet which it then tries to run as the superuser using sudo. My imagination is sparkled by so many possible ways to own someone's system right now.

Anyway, to test this is had a container with a terminal installed (in my case, I used sakura). Using a terminal app lets you run as the phablet user, no need to add another user. I used the libertine-container-manager CLI tools to install the curl command but the sudo command isn't available, because that would let you break containment, so the installation failed.

You're not going to be able to run contained applications from outside the container because that would break confinement.
