Hi, I’m working on a snap for the Proton Mail application. The repository is at pedro-avalos/proton-mail-snap and the listing is under the name proton-mail. Currently, I only have a beta release as per the snapcrafters template, so you should be able to install it using snap install --beta proton-mail. Let me know what you think!

Hi ! @pedro-avalos 
I tested your snap, it works well 
Why not use the name protonmail instead of proton-mail (the name seems available)?
Hi @baldeuniversel! Thank you for testing the snap 
I thought about using protonmail instead, but the package that Proton itself makes is under proton-mail.
Proton has been moving away from using “ProtonMail” and instead using “Proton Mail” for their branding, since their brand and ecosystem consists of more than just their email offering.

Please enable wayland and disable sandboxing for nvidia. I think that’d be awesome. For ref
@soumyaDghosh ! Did you mean ? 
#!/bin/bash
if [[ ! -n "$DISABLE_WAYLAND" ]] && [[ -n "$WAYLAND_DISPLAY" ]]; then
WAYLAND_OPTS="--enable-features=WaylandWindowDecorations,WebRTCPipeWireCapturer --ozone-platform-hint=auto"
fi
exec "$SNAP/opt/Element/element-desktop" --no-sandbox --disable-seccomp-filter-sandbox $WAYLAND_OPTS "$@"

Hi @soumyaDghosh , I’ve added the launcher wrapper and updated the beta to 1.0.6, let me know what you think!

I looked into the code, looks great!!! Just a question, does the chromium sandboxing work under nvidia? What if we just disable sandboxing in nvidia? Also, to add up, I am not sure if sandboxing works at all in electron based snaps, because the browser-support plug needs to be there, which is not for these electron apps. What do you think about that? Also, thanks a lot for taking your time and maintain it. May be we can upstream this also, if it gets stable?
Hi, sorry for the long delay, I have been with some travel and work the past few weeks. I don’t know what you mean about the browser-support plug not being there, it is in the snapcraft.yaml file, and it should auto-connect.
Sandboxing (ie chrome-sandbox), as far as I know, does not work with snaps; snapcraft will warn me if I try to copy the chrome-sandbox file (hence why it is excluded when priming). Unless I’m misunderstanding what you mean by sandboxing, I think I always need to disable sandboxing (ie use --no-sandbox in the launcher).
Let me know what you think and if I misunderstood what you are talking about (which is very likely honestly).
Heh, of course the snap broke just now when I bumped the version. Any help debugging this would be appreciated. It seems to only crash when on Wayland…

Hi @pedro-avalos.
Check to see if you have these “requirements” :
parts:
test-snap:
source: .
plugin: dump
stage-packages:
- libdrm-amdgpu1
- libgtk-3-0
- libatk-adaptor
apps:
test-snap:
command: bin/test-snap
plugs:
- network
- opengl
environment:
LD_LIBRARY_PATH: "$SNAP/usr/lib/$SNAPCRAFT_ARCH_TRIPLET:${LD_LIBRARY_PATH:-}"
Hm, I tried adding these to no avail. snapcraft seems to warn me that almost all of these are unused if I add them (except libatk-adaptor, but even that didn’t fix it). As a temporary workaround, I’ve decided to disable wayland using the environment variable DISABLE_WAYLAND (it seems this was done in the Discord snap recently too…)

@pedro-avalos ! Doesn’t it work even with wayland plugged in ?
@baldeuniversel , yeah, it had the wayland interface plugged in and it did not work. I am truly confused on what could have changed. I’ll try to investigate further after work.

It seems it’s an upstream issue? The snap seems to work with Wayland now (meaning it doesn’t crash). However, the content layout is messed up. So, until that is resolved upstream (See related issue upstream), I’ll keep Wayland disabled for the snap.
