Errors on Ubuntu 20.04

Hi

"Use registration from Devolutions Account" crashing the application is a known issue.
To help diagnose your SSH issue, could you please run RDM in a terminal (ctrl-alt-t to open a terminal and type remotedesktopmanagerfree)
If you have a stack trace, could you please post it here?

Regards

Hi Jonathan.

I've recorded my screen.

I'm sendding in attachment.

The output on my ssh:

"remotedesktopmanager.free

I can't send the video.

Maybe it's an unsupported file type

You can send it directly to me or use a file transfer website if you want.

Nevertheless, I'll setup a test environment to try and replicate your issue.

OK, This is the video:
https://drive.google.com/file/d/1tjk8QDoDt2L2GZ9U7tmetroF3m0o9siT/view?usp=sharing

On the website, the link to download RDM Free was still pointing to an older version.
It should be fixed and you should be able to now download 2020.2.1.0.
Per my testing, registering with a devolutions account should now be working.

You can also give SSH a try.
SSH, with version 2020.2.1.0, is working for me.
I've found a bug related to the session's port. As long as your session doesn't require a port other than 22 it should work.
The bug has been fixed internally and will be available in the next release.
If it's something you need, let me know, I'll send you a build with this issue fixed.

Regards

Hi Jonathan.

All works good now with the new version 2020.2.1.0.

Thanks for your support.

The "Registering with a Devolutions Account" issue still seems to be present in the latest release, unless I've goofed and done something wrong which I don't believe.
Every time I try to Register with a Devolutions Account it crashes and gives me this error:

Remote Desktop Version: 2020.2.1.0
Ubuntu: 20.04 LTS

Can you check in /home/yourusername/.rdm the content of RemoteDesktopManagerFree.log and let me know if there's additional information in there?

After trying to "Register with a Devolutions Account" this is what prints to RemoteDesktopManagerFree.log

Thank you for provising the information.
I will continue to investigate this issue.

I installed 20.04 on a vm and downloaded RDM 2020.2.1.0 and had no problem registering with a devolutions account.
Based on the log, I can see two reasons why it wouldn't work.

1. For some reasons, https://login.devolutions.com is not reachable. Could you please try to ping this address to make sure RDM can reach it?
2. ca-certificates were missing and mono certificates weren't generated when you installed RDM.

To check this, can you make sure the folder /usr/share/.mono/new-certs/Trust/ exists and contains something?

Hello again,

I am not getting any response when pinging "login.devolutions.com".
To make sure it's not blocked locally on my firewall, I ran a quick tracepath and it seems to get out fine. It got stopped before reaching the devolutions server, but I would assume that is just ICMP being blocked along the way.

In regards to the folder "/usr/share/.mono/new-certs/Trust/". It exist and has multiple files.

I will add more logs in RDM to hopefully get a better idea of what is happening.
I can send you a build with the additional logging if you would like?

Yes, I'd be happy to.
Would you like me to clean/purge the currently installed version any other way than using regular apt/dpkg purge?

I've sent you a private message with more details.

Hey,
Thank you for providing a custom build to help debug the issue.
To uninstall the older version I used sudo apt purge remotedesktopmanager.free
To install the newer version I used sudo apt install ./RemoteDesktopManager.Free_2020.2.1.0_amd64.deb

Would like to mention that I noticed no delay in terminal verbose output and the log files being created and populated.
Let me know if I missed some data output from somewhere, as the output I've found seems to be very similar to the ones I had before.

Terminal verbose output when starting application through terminal using "remotedesktopmanager.free":

Ok, based on the log you sent me, the problem is with the mono doesn't like the SSL certificate we are providing.
Could you please delete the .mono folder in "/usr/share", purge rdm and reinstall?
This should force the ssl certificates to be generated again.

Amazing, that seemed to have fix the issue!
Cheers for all the superb help and support.

Glad to hear this fixed your issue.
