Ckan: [Bug] Unhandled Exception after launch on Linux

[StephaneMangin]

Background

• Operating System: Ubuntu 18.04.3 LTS
• CKAN Version: 1.26.8
• KSP Version: 1.8.1

Have you made any manual changes to your GameData folder (i.e., not via CKAN)?
Yes for Real Solar System and Textures (but already works on 1.26.6)

Problem

Null reference exception

Steps to reproduce
launch ckan by command or by desktop link

CKAN error code (if applicable):

What version of Mono do you have?

[DanFraserUK]

I've got the same issue.

CKAN version : 1.26.8 - installed from ckan_1.26.8_all.deb
Mono : Mono JIT compiler version 5.18.0.240 (Debian 5.18.0.240+dfsg-3 Mon Jun 24 08:50:44 UTC 2019)

I'm happy to go bashing stuff into the terminal to help out.

[HebaruSan]

Thanks @DanFraserUK. Can you try the ckan.exe download instead? They are different builds at this point and the one in the .deb also had problems on Windows (see #2972).

@StephaneMangin, did you install the .deb file as well?

[DanFraserUK]

Great minds think alike eh? I've literally just downloaded the exe, placed it where my directory structure dictates and ran mono /media/Games/Windows/CKAN/ckan.exe and it's running perfectly. It has even detected the old CKAN data in the KSP backup I did after having to reinstall Kubuntu yesterday so I don't have to faff about with detected but not modifyable installed mods.

I'd prefer native though of course!

[HebaruSan]

Thanks! That helps to narrow down the problem.

Looks like we need to roll back to building on an older Mono. Too bad we can't just take upgrades to get fixes and improvements, etc...

[StephaneMangin]

Thanks @DanFraserUK. Can you try the ckan.exe download instead? They are different builds at this point and the one in the .deb also had problems on Windows (see #2972).

@StephaneMangin, did you install the .deb file as well?

Yes it was from the deb.

[HebaruSan]

@StephaneMangin, the .deb download has been replaced, you can try downloading and installing it again.

[DanFraserUK]

I can confirm it's working on my system now.

Thank you very much!

[StephaneMangin]

@StephaneMangin, the .deb download has been replaced, you can try downloading and installing it again.

It works ! Thanx
