Same error on Ubuntu 20.04. Did you make a Linux client and did not even try it on Ubuntu?

[Eric R | Senior Technical Support Engineer]

Hi Paaland,

Thank you for your feedback. Rest assured, we are testing Linux and specifically Ubuntu. However, we are still actively working on this issue. As gratitude for your feedback, I have increased the priority of the associated Bug Report. I encourage following the item to receive future updates.

So, it's now May of 2020 and this is still a issue on Ubuntu based distributions. That bug report is tagged an Unplanned. Are you guys going to fix this? I tried this last year this time and had the same results and read that we needed to wait for a fix. I've been getting emails about the release of Fiddler Everywhere and how I should join all these webinars about it, but I can't even run it... At least give us a work-around, or something.

[Eric R | Senior Technical Support Engineer]

Hi everyone,

I would like to thank everyone for their patience and understanding with this. As we are moving Fiddler to other platforms issues can arise during development and we understand that this can be frustrating.

However, the latest beta release of Fiddler Everywhere is available at https://www.telerik.com/fiddler-everywhere/insiders and includes the fix for Ubuntu. I recommend ensuring the latest ApppImage is downloaded and in use.

Additionally, I have tested the latest version on Ubuntu 19.10 and 20.04. I can confirm that it is working as expected. For a visual reference see the below screenshots.

19.10

20.04

As always, we thank you for your feedback and your excitement to use Fiddler on Linux. If you should experience any additional issues, feel free to post a new forum thread detailing the issue.
