Snap Maintainence Thread

[soumyaDghosh]

With the latest attempt, I have made it possible to use the two finger pinch to zoom in.
This is the snapcraft.yaml file. Check this out. I hope this is now much much stable, with core22.

snapcraft.yaml

name: saber # you probably want to 'snapcraft register <name>'
base: core22 # the base snap is the execution environment for this snap
version: '0.9.8' # just for humans, typically '1.2+git' or '1.3.2'
summary: Single-line elevator pitch for your amazing snap # 79 char long summary
description: |
  This is my-snap's description. You have a paragraph or two to tell the
  most important story about your snap. Keep it under 100 words though,
  we live in tweetspace and your description wants to look good in the snap
  store.

grade: devel # must be 'stable' to release into candidate/stable channels
confinement: devmode # use 'strict' once you have the right plugs and slots
architectures:
  - build-on: amd64

Thanks!

[soumyaDghosh]

Hi, @adil192, I am also learning flutter and started a new project of a full-fledged calculator. It'd be great if you can share some of your experiences and best practices. Is there any way to directly connect with you, or any matrix group which you said you'll create.

[adil192]

Sorry I'm not looking for anything like that at the moment

[soumyaDghosh]

Hii, can you kindly pull the trigger for build after each release? This way the updates can be released for snaps just on time

[adil192]

How would I do that?

[adil192]

Okay I'll try to remember

The build log, where it failed. The snap compiles the flutter from stable branch of flutter. Do you need a more new branch?

[adil192]

No I'm using the stable branch (3.13.0 which just got released to stable).
Also note that I've rolled back the v0.15.0 Saber update due to a bunch of issues

[soumyaDghosh]

I know, it's due to the shorthand we used. Asked this in the forum long ago, guess you missed it.

https://forum.snapcraft.io/t/architectures-short-hand-not-working-as-expected/37006

[adil192]

Ah, I'm not subscribed to that. Thanks for the PR

[soumyaDghosh]

It's okay. That's what my duty is. 😃

[adil192]

No sorry. This is still an unofficial distribution of Saber and any concerns that apply to other apps not published by the official devs also apply to this one.

[soumyaDghosh]

You test the snap yourself, check the code, as it's in your repo. You don't need to believe me for it. But, you yourself, tried to make a snap, is it because that I made the snap and published? I am sorry if that's the case. But please think about it. As you have the highest userbase with the snaps. 204 ACTIVE INSTALLS at the moment of writing this.

[adil192]

I don't test the snap myself. I haven't tried to make a snap*. And 204 installs isn't the highest userbase. Please don't ask another time

*Unless you mean triggering a build, which I'm just doing as a favour for you since you asked

[soumyaDghosh]

I haven't tried to make a snap*

Ummm.. I actually saw an unfinished snap manifest before in your repo. So, I said it.

https://github.com/adil192/saber/tree/v0.7.0/snap

204 installs isn't the highest userbase

And for containerized packages, i.e. flatpaks, appimages(not sure) and particularly in linux, it's the highest.

Please don't take these otherwise, and forgive me if I am being rude here.

[soumyaDghosh]

EDIT: Permission issues

[soumyaDghosh]

@adil192 kindly connect this repo in snapcraft by logging in through your github account. I don't have that permission anymore, and I don't think it's necessary as you can do it.

[adil192]

Done!

[soumyaDghosh]

Thank you! Snaps building!

[adil192]

@soumyaDghosh Can you add the gstreamer dependency to the snap:

// https://snapcraft.io/saber/builds/2480357

:: [  +28 ms] --   No package 'gstreamer-1.0' found

Also the build of v0.23.1 will fail anyway since Flutter 3.22.0 was just released but isn't compatible. That's fine for now and will be fixed in the future.

[adil192]

@soumyaDghosh After #1263 the snap build is now missing gstreamer-app-1.0

[adil192]

I added the dependencies from the README and now the build is failing where expected for the latest version (#1103 (comment))

[soumyaDghosh]

I am very sorry, as I could not give time to look into it. But, yes that's it. You didn't need to add libsecret1 though. But, no problem. I am once again very very sorry.

[adil192]

I am very sorry, as I could not give time to look into it. But, yes that's it. You didn't need to add libsecret1 though. But, no problem. I am once again very very sorry.

I don't see any harm in dependencing on it explicitly since the snap base could remove it as a pre installed package at any time

Nahh, they'll never. All the browsers depend on it.
