Same here for me. Has been working for a few months and then stopped after an update. In this update, the lunch icon did change.

hreidar on 8 Jul 2020

Hi, any news on this. Is it possible to revert back to a working version? Snap only shows this broken 3.5.1

hreidar on 25 Jul 2020

Having older versions on snap would be highly appreciated!

The above command is working on latest debian, not on Ubuntu 20.04

Please give us older working versions in snap

ok, will test when 3.5.2 enters snap repo

hreidar on 5 Aug 2020

3.5.2 is now out containing a fix for this. Please re-open if this is still an issue.

nevalla on 6 Aug 2020

Hi @nevalla , the app does not lunch a GUI on Ubuntu 20.04 after updating and I still see the following error using a trick that fixes that problem on Debian.

@nevalla, I notice that you are talking about 3.5.3, I don't see that in my snap repo at this time

hreidar on 6 Aug 2020

Issue for me was fixed on 3.5.2. (_got from snap edge_)

What is weird is the app starts a default terminal (bash) and gets executed upon that. I have a wrapper on my terminal (bashrc) which causes problem for the app to run.

arash-bizcover on 6 Aug 2020

where are the app logs located, anyone knows that so I can post debug logs?

hreidar on 6 Aug 2020

@arash-bizcover which distro/version are you using?

hreidar on 6 Aug 2020

@hreidar I tested on my local ubuntu 18.04 as well as a new 20.04(on vm)

arash-bizcover on 6 Aug 2020

ok, I'm using a recent install on Ubuntu 20.04 and I have not, to my knowledge, changed anything. The app worked at one time before some upgrade but I have no idea why things broke

hreidar on 6 Aug 2020

Hi, I managed to lunch the GUI by running sudo kontena-lens from terminal. The app does not lunch GUI if I double click the lunch icon.

hreidar on 6 Aug 2020

@nevalla, I notice that you are talking about 3.5.3, I don't see that in my snap repo at this time

Sorry...I meant 3.5.2

nevalla on 6 Aug 2020

ah damn!
I ran the app as root and it corrupted my root folders .....

@hreidar, this indicates that your issue is somehow related to cluster store migration:

Need to investigate that a bit further.

why is this app developed like this 😞

Ouch. That logic is coming outside of Lens. Perhaps Snap(?) is doing that?

nevalla on 7 Aug 2020

Yes I apologise, it was not Lens.
It was this damn Snapd!

arash-bizcover on 7 Aug 2020

@hreidar If possible, please could you remove ~/.config/Lens/lens-cluster-store.json and start from fresh. After that you have to re-add your clusters to Lens.

nevalla on 7 Aug 2020

@nevalla I do not have any ~/.config/Lens/lens-cluster-store.json on my machine. I did remove the app and add it again at some point when I was debugging. Now it seems that I'm unable to start it from the command line using sudo kontena-lens as I managed to do yesterday.

I am seeing the same issue:

On the same system Lens-3.5.2.AppImage seems to work fine for me.

webwurst on 10 Aug 2020

same here, the AppImage of Lens-3.5.2 works

hreidar on 10 Aug 2020

Hello there:

I ran into the same issue using master branch...
The issue seems to be that the reference to the electron app is undefined:

https://github.com/lensapp/lens/blob/master/src/migrations/cluster-store/3.6.0-beta.1.ts#L12

To be able to start the app anyway on linux, set this in the store:

- $HOME/.config/LensDev/lens-cluster-store.json

{
    "__internal__": {
        "migrations": {
            "version": "3.6.0-beta.1"
        }
    }
}

You'll still get some store errors but it starts anyway (skips the migration)

Nox-404 on 16 Aug 2020

Another solution for me was to delete the LensDev & Lens config directories...

Nox-404 on 16 Aug 2020

I'm closing this now, since the original issue is already solved. Lens 3.6.0 is out now. Please open new issue with new details if this is still issue there.
