Problems registering RDM on Linux closes at registration time.

Hi,

Most of the time, when the login fails, it's a problem with the generated certificates.
The installer post install script takes care of that but on 20.04, I've seen instances where the generated certificates were corrupted.
To make sure this is not the issue, make sure the ca-certificates is installed and up to date.
Then delete the .mono folder in "/usr/share", purge rdm and reinstall.
This should force the ssl certificates to be generated again.

Regards

Hello!
I have no .mono folder in system, how I can regenerate certificates?
I already try to just reinstall RDM, it's not help.

OS
Linux version 5.4.64-1-MANJARO (builder@d467f31eaa7a) (gcc version 10.2.0 (GCC))

RDM version
2020.2.4.0-1
Installed via AUR
https://aur.archlinux.org/packages/remote-desktop-manager-free/

Hi,

Indeed, reinstalling RDM would only be helpful if your package has a post install script like the .deb does.
You might want to take a look at this thread I created listing everything needed to successfully run RDM.
https://forum.devolutions.net/topics/34347/installing-rdm-on-an-unsupported-distro

To generate the mono certificates, you can follow these steps

• Make sure the /usr/share/mono/new-certs/Trust exists otherwise, mkdir -p /usr/share/.mono/new-certs/Trust
• If the previous folder didn't exist or was empty, create the mono certificates using command "for f in /usr/share/ca-certificates/mozilla/*.crt ; do cp $f /usr/share/.mono/new-certs/Trust/$(openssl x509 -noout -hash -in $f).0 ; done"*

* On some systems, the ca-certificates are located in /usr/share/pki/trust and have a pem extension. In this case, replace the previous command with "for f in /usr/share/pki/trust/*.pem ; do cp $f /usr/share/.mono/new-certs/Trust/$(openssl x509 -noout -hash -in $f).0 ; done"

Hope this helps you.
Regards

Thanks! it's help me to understand how to fix it.

FYI
Arch like distributive has not following folder: /usr/share/ca-certificates/mozilla/
so I run following script to do what you propose

mkdir -p /usr/share/.mono/new-certs/Trust
sudo trust extract --filter=ca-anchors --format=pem-directory-hash /usr/share/.mono/new-certs/Trust/

Glad to know you were able to fix the issue.
Thank for the trust extract command, I'll add it to the sticky post, it might help others.

I believe this is now fixed in the AUR packages for both the free and enterprise version

Thank you to whoever is maintaining those packages.

"I believe this is now fixed (...)"
It is not.
5 minutes ago I checked latest from AUR on Manjaro pkgver=2021.1.1.4 and its still crashing on "Register with Devolutions Account".

mkdir -p /usr/share/.mono/new-certs/Trust
sudo trust extract --filter=ca-anchors --format=pem-directory-hash /usr/share/.mono/new-certs/Trust/

This ^ also does not work for me.

Hi,

If you run remotedesktopmanager from a terminal, do you have more information about the crash?
What is the output of the trust extract command?

This is my output.
1st line is ok. I mean not ok, but rdm not crashing on it -> "(RemoteDesktopManager.Free:128493): .( ... ) /tmp/dbus-7aJQpioHAQ: Nie ma taki
ego pliku ani katalogu.
1st line shows at start, and rdm works well. I can add stuff, connect to sessions etc.
After click to OK on checked "Register with Devolutions Account" the rest shows up.

$ remotedesktopmanager.free

This is just note for support.
Registration via serial number works ok. -> for me - problem solved.

This is the kind of error RDM encounters when mono certificates are absent or invalid.
As long as RDM doesn't try to make any other https calls, you should be fine.

Otherwise, we'll have to found out why this command isn't working
sudo trust extract --filter=ca-anchors --format=pem-directory-hash /usr/share/.mono/new-certs/Trust/

Maybe this output tell something.

$ trust extract --filter=ca-anchors --format=pem-directory-hash /usr/share/.mono/new-certs/Trust/
p11-kit: format requires a purpose, specify it with --purpose; defaulting to 'server-auth'
p11-kit: directory already exists: /usr/share/.mono/new-certs/Trust/

The same output is for # at 1st line (root).

Looks like the Trust folder already exists.
Is the Trust folder empty? If it is, you can simply delete it and run the command again.

Its empty, owned by root:root

# pwd
/usr/share/.mono/new-certs/Trust
# ls -al
drwxr-xr-x 2 root root 4096 06-30 00:21 .
drwxr-xr-x 3 root root 4096 06-30 00:21 ..

edit:
after deleting Trust subdir and running command, Trust is created again and its populated by many certificates .pem.

You can safely delete the folder and run

sudo trust extract --filter=ca-anchors --format=pem-directory-hash /usr/share/.mono/new-certs/Trust/

Seems like You found solution.
Registration via "Register with Devolutions Account" works well now.
Thank YOU.
[SOLVED]

My pleasure.
