Could you try this with our AppImage, from the Ultimaker website or from the releases here at Github? The PPA has had some issues recently with the back-end being more modern than the front-end. The back-end then goes looking for a setting it needs to slice which doesn't exist in the front-end yet, and then the engine crashes which makes it look like slicing freezes.

We don't maintain that PPA, that's done by @thopiekar. Issues for that PPA should be posted here: https://github.com/thopiekar/Cura-packaging/issues but recently he hasn't had much time to maintain it.

Alright. I am going to download & run .AppImage from official website that you provided, then let you know the result.
Thank you for quick reply.

[krishnaTORQUE]

Its working like a charm.
Thank you so much.

[thopiekar]

That is partly true. I simply don't support Ubuntu versions before Cosmic
(or maybe Bionic - forgot it actually). The problem is basically that Qt is
too old and Cura won't run due to the new UI.
Therefore I recommend upgrading Ubuntu and using the stable PPA. For the
master PPA there is generally no support.

But agree, I should make a cleanup on the stable PPA and remove all the old
packages.

Cheers

I am using 19.04 Disco.
I notice that 3.4 have some display issue like no label on button etc. It this due to Qt framework?

[thopiekar]

3.4? That sounds like you are using Canonical's packages.
For that again no support, too.

[krishnaTORQUE]

No I did once to try when 4.2 PPA version was not working.
How ever right now I am using 4.1 from official website .AppImage with Ubuntu 19.4 working fine.
It will get even better if we get stable version of PPA support.
I tried PPA of cura & cura-master both did not work as well.

[thopiekar]

Hmm, using Ubuntu 19.04 here, too. Cura starts from stable PPA fine with Nvidia gfx here.
Can you give me more details? Hardware? Logs?

Thanks!

[krishnaTORQUE]

I am 100% I did not.
I removed & clean every time I installed another version of Cura

I just found time to test it on my computer (KDE + NVidia GFX) and well application works fine without glitches and slices as it should.
