Install applications in Ubuntu core

Question

I installed Ubuntu Core and found that it used Snap for application installation. I want to install many applications on this system such as firefox, chrome, and many more. How can I do it? And is it possible to install apt-get or yum any how?

Solution 1

To get some apps not snapped yet on my Ubuntu Core arm i used the classic snap:

sudo snap install classic --devmode --edge

then

sudo classic

then apt-get is available

Solution 2

No, Ubuntu Core is completely snap-based: apt is not available. Ubuntu Core mostly targets headless or kiosk-type devices, and as such doesn't ship with a window manager etc. Kiosk software typically uses Mir. You probably don't want it for a normal desktop environment; you can install snaps on the classic desktop release.

You can search for apps using snappy search firefox for example. Once you find the app, you can run sudo snappy install appname to install it. Core is not meant to work with apt-get, although I did hear a case of someone using it before.

@Dorian it returns: The search "firefox" returned 0 snaps

Thanks Kyle, I wan to use U-Core for Digital Signage solution, and data I want to show on Firefox or Chrome. Also I have one daemon which requires packages like, npm, nodejs etc.

Ah, that's totally doable. I'm not sure that Firefox or Chrome will work with Mir, though-- you may need to use more of an embedded browser, I'm not sure. This walkthrough might include more information. Regarding your daemon, you simply need to package it as a snap. npm and nodejs are supported within Snapcraft, so just read up on how to create snaps and you should be good to go.
