Quick example on building a .NET Snap package

SnapSharp

SnapSharp is a simple Avalonia .NET application that targets the Linux operating system. It's main raison d'etre is to demonstrate how to package a .NET Linux desktop application into a Snap.

How to Build

1. Clone this repository
2. Build the Snap package with

$ snapcraft --debug --use-lxd

• --debug to get a shell into the build container in case an error occurs mid-build.
• --use-lxd to use a container as the build infrastructure.

3. Install the Snap on your system with

$ sudo snap install snap-sharp_0.1_amd64.snap --devmode

4. Run the app

$ snap-sharp

Further Observations

Multipass not working

Building this Snap with Multipass was not working with the following error:

launch failed: Remote "snapcraft" is unknown or unreachable.

I resorted to using LXD as an alternative, which worked flawlessly.

Font family error

By the time I was done with the Snap package, the application was failing to launch with the following exception:

Unhandled exception. System.InvalidOperationException: Default font family name can't be null or empty.

As a workaround, I had to add the following NuGet packages to the .csproj project file (as per this comment):

<PackageReference Include="SkiaSharp.NativeAssets.Linux" Version="2.88.3" ExcludeAssets="all"/>
<PackageReference Include="SkiaSharp.NativeAssets.Linux.NoDependencies" Version="2.88.3" />
