Cura 🚀 - Could not connect to the Cura package database

Check if your network connection is working properly. Check also your firewall is not blocking requests.

Everything works. BTW I can download plugins using direct links from here https://api.ultimaker.com/cura-packages/v1/cura/v4/packages

Maybe something wrong with .AppImage running on Debian.

How can I get logs from your AppImage bundle ?

rumatoest on 12 Jul 2018

If you go to _Help > Show configuration folder_ and there you can find a cura.log file. Please attach it here and maybe we can find something there.

Please share the whole log (ideally external file), the section you've clipped here does not contain any errors.

rumatoest on 18 Jul 2018

I have the same issue.

Cura: 3.4.1
OS: Ubuntu 18.04

Let me know if I can provide more information.

thattolleyguy on 30 Jul 2018

Seems like an SSL issue. We've had these before, but that was using Python's requests module not Qt network. Ping @LipuFei

ChrisTerBeke on 30 Jul 2018

Same problem here, both with Cura 3.4 and 3.4.1 (Cura-3.4.1.AppImage) on standard Ubuntu 18.04

tmbdev on 31 Jul 2018

Saw this before, probably missing SSL libraries in the AppImage.

For Dev: CURA-5608

LipuFei on 31 Jul 2018

Same issue with Cura 3.4.0 and 3.4.1. under Debian Stretch
Cura 3.3.1 works

fcerbell on 31 Jul 2018

Yeah, Cura 3.3 didn't use a secure HTTPS url yet....

ChrisTerBeke on 31 Jul 2018

Update :
Does not work on my Debian Stretch upgraded, but works from another stretch freshly installed.

fcerbell on 31 Jul 2018

Is there any difference in the SSL package that's installed on those machines?

ChrisTerBeke on 31 Jul 2018

Working Stetch :
~ $ dpkg -l | grep libssl

fcerbell on 31 Jul 2018

Maybe it's the libssl-dev packge that is causing the certs not to be verified?

ChrisTerBeke on 1 Aug 2018

Found a related issue: https://github.com/wkhtmltopdf/wkhtmltopdf/issues/2938
Looks like certain distros have dropped SSL v2 and v3 support completely in their ssl packages. Our build system is CentOS 6.9 which may have the same issue.

LipuFei on 1 Aug 2018

😕1

@ChrisTerBeke OK, turns out we are missing libssl.so and libcrypto.so in the AppImage, although libssl.so.10 and libcrypto.so.10 are there. I just fixed this problem for master builds that it will create symlinks libssl.so and libcrypto,so and Toolbox now works.

LipuFei on 1 Aug 2018

🎉1

Given the focus we put on the Toolbox, I think it's worth asking @Appesteijn about making a 3.4.2 release with some of these fixes before next month.

ianpaschal on 1 Aug 2018

@rumatoest , @thattolleyguy , @tmbdev , @fcerbell . So far we have a solution for this issue, but I cannot perform a good testing because on my machine I have Ubuntu and Cura works fine. I have uploaded Cura (master version) to the internet for testing. Could you please test this build for us and give feedback, whether it works properly or not.

The link will be available 7 days.

alekseisasin on 1 Aug 2018

Tested and works. I'm able to browse the plugin repository just fine. Thanks!
I also installed the octoprint plugin and it appears to be working correctly

thattolleyguy on 1 Aug 2018

It works,

P.S. but it totally screwed with my configuration. Started only after reseting previous config

rumatoest on 1 Aug 2018

Same here, now I can browse the plugins, select a plugin (tried with Octo print also), install it. It also screwed my configuration. I dont matter, I prefer to have Octoprint ;)

Thanks a lot

fcerbell on 1 Aug 2018

I'll create a 3.4.1 build with this fix for you. The master build is not really stable.

LipuFei on 1 Aug 2018

Will this be released as 3.4.2? Or will we just need to use a special 3.4.1 build?

thattolleyguy on 1 Aug 2018

I want to talk to our product owner about making a 3.4.2 release with this and other bug fixes when he returns from vacation next week but can't guarantee that; might have to just wait until 3.5 if master is not that stable right now.

@LipuFei We prefer to not be releasing unofficial builds because it makes it reaaaaally hard to keep track of what version people are using. I think it's better to leave it at the test version @alekseisasin posted which will be up for 7 days. If it's fixed for everyone, release the fix officially in 3.5 or 3.4.2.

Hi, I have the same problem, only on the Windows 7 platform. Help please.
