unable to resolve host address ‘appimage.moto9000.moe’

Is that the correct address?
Please upload the AppImage to https://github.com/vircadia/vircadia/releases, then we can use that. Thanks!

[JulianGro]

@probonopd The address is correct and works fine on my network.
Could you try rerunning it?

[probonopd]

At the time when I tested it it did not work, also on my local machine. (Now it does - but how long before it goes down again?)

I see that the domain is linked from https://vircadia.com/download-vircadia/#linux - so I think we can consider it trusted by the project.

[JulianGro]

What DNS are you using?

[probonopd]

Whtever my provider provides ;-) now it is working btw.

[probonopd]

There is a permissions issue with the AppImage:
/bin/bash: /run/firejail/appimage/.appimage-11546/AppRun: Permission denied

Looks similar to #2102.
Please make sure that the top-level directory is readable by everyone.

Reference:
netblue30/firejail#2690

[JulianGro]

Yeah I am not sure if it makes sense for me to extract the AppImages and manually sqash them for every update.
Seems like this should be fixed in appimagetool instead.

EDIT: the test to see if it's the problem doesn't work btw.

motofckr9k@motofckr9k-mint-desktop:~/git$ unsquashfs -ll Vircadia-x86_64-release-latest.AppImage /
Can't find a SQUASHFS superblock on Vircadia-x86_64-release-latest.AppImage
motofckr9k@motofckr9k-mint-desktop:~/git$ 

I just ran it instead and looked at my /tmp/ folder.

[probonopd]

the test to see if it's the problem doesn't work btw.

You need to provide the correct offset to unsquashfs, with you can get by running ./Vircadia-x86_64-release-latest.AppImage --appimage-offset.

This is still a bug in AppImageKit AppImage/AppImageKit#1032
I am not up for manually unpacking and repacking the AppImage for every update if it works for all end-users.

[JulianGro]

Yeah it looks like the virtual graphics adapter doesn't support the minimum required OpenGL version or even the minimum OpenGL ES version needed for a mobile build, so this will never run properly.
I assume if it creates a screenshot it is either a black window or a black window with the toolbar showing on the bottom.

Our test machine has no actual GPU. How can we still take a screenshot?

[JulianGro]

You cannot. Like I said, you will get a black window. If you are lucky it will show you the toolbar.

I tried adding AppStream information with screenshots in the past, but apparently that isn't as easy as it seems: AppImage/AppImageKit#603

[JulianGro]

Then again, if it passing the tests would be good enough for you to include it, then we can just have it have a broken screenshot until AppImage/AppImageKit#603 is fixed.
That would be next Vircadia release though since this is only an experimental AppImage.

[probonopd]

https://appimage.github.io/simple-appstream-generator/ is my answer to #603 - does it work for you?

[JulianGro]

No. I run into exactly the same issue as descripbed in the opening post of AppImage/AppImageKit#603

[probonopd]

Remove appstream-util from your system and retry, please.

[JulianGro]

Seems to have worked. It should make it into the next release.

[JulianGro]

Almost forgot about this.
@probonopd the latest release should be perfectly fine to merge now.

[probonopd]

Is it really just showing a black screen when not connected to the internet?

[JulianGro]

Is it really just showing a black screen when not connected to the internet?

@probonopd No it is showing a black screen when on a machine that doesn't support proper OpenGL. That is one of the reasons there are screenshots in the AppStream.
When first starting the app you spawn in a "serverless tutorial" which doesn't need a connection to the internet.

[JulianGro]

Is there anything keeping this up?
Like is there issues with using screenshots from AppStream currently?

[probonopd]

Does it no longer show a black screen when the computer is offline? That is required for the test to be considered a "pass".

[JulianGro]

It doesn't show a blackscreen when the computer is offline.
It only shows a blackscreen because your test doesn't support OpenGL 4.1 or higher.
