Ubuntu – How to create an architecture independent snap

packagingsnap

I've created a small snap package that contains no compiled architecture dependent code. When I build the package it ends up named like ..._amd64.snap, but there is no reason why the program within the snap couldn't run on any other architecture.

So is there a way I can build the snap so it can be installed on any architecture?

Searching around a bit, I found the solution in the packaging for the classic snap. Edit the snapcraft.yaml file, and add the following at the top level:

architectures: [ all ]

Now when building the snap, the resulting file name will be ..._all.snap, and the architecture in prime/meta/snap.yaml will also be set to all rather than the build system's architecture.

The resulting snap can be installed on any system regardless of its architecture.

Ubuntu – “stop-timeout is not an integer” when generating snap package – why

snappy build and the tool that reviews the resulting snap are provided in two different packages developed in separate source repositories but they need to be kept in sync, the most likely cause of this particular issue is that they are indeed not in sync. Getting the latest versions of these packages will most likely fix this.

If you've done a release upgrade the ppa where the tools are published probably got disabled, you can simply add it again by running

sudo add-apt-repository ppa:snappy-dev/tools

Then update and upgrade

sudo apt-get update
sudo apt-get dist-upgrade

Replace apt-get for apt if you prefer using it.
