[Cura 4.4.1 stuck starting up on Ubuntu]

I'm downloaded Cura 4.4.1 for Linux. It hangs on startup. Here's a screenshot and a couple of log files (.local/cura/stderr.log and .local/cura/cura.log. I've has this problem since version 3.6 (worked okay).

stderr.log cura.log

Yep - that's it. It's an old NVIDIA GT218 with a GeForce 8400 that supports OpenGL 2.1 - I guess it's time to upgrade!

Thanks for the info.

Hi,

I'm new to Cura. I'm running Cura 3.6 from the appimage (Ultimaker_Cura-3.6.0.AppImage) on Ubuntu 18.04 and I also don't have a play button. I do not have compatibility mode forced in the General settings. As far as I can tell OpenGL is enabled and the few tests that I've tried all work. Could this be because I'm running from the appimage and the necessary libraries are missing?

[could not connect to package database]

I have two Ubuntu 18.04 systems: an Asus-X551M and a Dell-N7010. Cura-3.4.0.AppImage "Toolbox->Browse" packages works on the Dell but not the Asus. The same for Cura-3.4.1.AppImage. Very weird.

just fired up the 3.4.0 appimage on my Ubuntu 18.04 system and it worked so something is less broken.

Ah - so you did - your post was lost in one of my searches for "cura AND connect" - I will wait for 3.4 to appear in the PPA.

Looks like at least 2 of us have this problem. Unfortunately there is a lot of confusion about which version is causing this problem. I am currently using Cura 3.1.0 - this error occurred when I tried Cura-3.4.0.AppImage which I picked up at https://ultimaker.com/en/products/ultimaker-cura-software.

 

I think the multiple forks are what's causing the problem.

[logical operators not working]

well - as I said I was looking for the keywords "cura" and "connect" which yielded a boatload of hits most of which didn't apply. The search page suggested I try using the operator "AND" as in "cura AND connect" - I did as suggested. That yielded another boatload of results most of which were useless in one way or another.

 

All of this isn't the problem - the PROBLEM is that now the search page is suggesting that I try "cura AND AND AND connect" among other possibilities.

 

I started all this from https://community.ultimaker.com/

[could not connect to package database]

I went to Toolbox -> Browse Packages and received the diagnostic

 

    Could not connect to the Cura Package database. Please check your connection.

 

There is nothing wrong with my "[internet] connection" so I don't understand this diagnostic.

I'm using Cura 3.4.0 on Ubuntu 18.04

I tried searching for "cura AND connect" which didn't work too well. The suggestion under the search box was

   

• The phrase "cura AND connect"
• cura AND AND AND connect
• Newest results first
• cura AND connect in content titles only

 

which suggests to me that the AND didn't work because it suggested "... AND AND AND ..." which is ridiculous.
