Classic on Core 18

snap
1

I’m trying to install classic on the core 18 image for Pi 3B+.

I did sudo snap install classic --edge --devmode then sudo classic.
I then got:-

This version of classic was build for Ubuntu Core 16. You appear to be using
a different version of Ubuntu Core. You can install different versions of                               
the classic environment, e.g. for Ubuntu Core 18:
                                                                                                         
    sudo snap install --channel=18 classic

That doesn’t work.

popey@localhost:~$     sudo snap install --channel=18 classic

What should I do?

we have never released classic to stable, if michael did a core 18 build yet i wouldnt expect it to be in the stable channel either… perhaps try something like --channel=18/edge or edge/18 ? (also do not forget the --devmode flag)

Note that from my paste there is no 18/edge.

However, that’s on a pi. On my laptop, I see it, so it looks like there’s just no armhf classic snap yet.

Just following up, I am also experiencing this issue. Anyone know if classic channel 18 will be available on arm anytime soon? I have tried finding this snap in both Ubuntu Core 18 for armhf and Ubutunu Core 18 for arm64.
