Key exchange was not successful

Question

Key exchange was not successful

Closed this issue 4 months ago · 7 comments

When i rebooted my computer last week, the browser integration stopped working. When pressing the refresh button on the extension, I get the message "key exchange was not successful." Before the reboot, it did work.

Expected Behavior

Extension connects to my database and works.

Current Behavior

Doing sudo strace -f -p $(pgrep firefox) 2>&1 | grep keepass as described in the troubleshooting guide gives me no line that indicated that ~/.mozilla/native-messaging-hosts
is being read.

ps aux shows that there is no keepassxc-proxy process.

Debugging the extension in firefox gives me the following logs:

In the past, I have used the flatpak permission-set webextensions org.keepassxc.keepassxc_browser snap.firefox yes trick to get the extension to run, this does not work anymore :(

I'd be grateful for any help :)

Best, Juri

It's possibly a Snap problem that we can do nothing about. You can also check: https://github.com/keepassxreboot/keepassxc-browser/wiki/Troubleshooting-guide#6-apparmor-with-ubuntu

Thank you. After adding the rules to /etc/apparmor.d/usr.bin.firefox, the command sudo aa-enforce /etc/apparmor.d/usr.bin.firefox fails with the following output:

ERROR: Syntax Error: Unexpected path entry found in file: /etc/apparmor.d/usr.bin.firefox line: 2

Answer 3 · 2024-01-31T11:30:41.000Z

That would mean you didn't add the lines correctly

Answer 4 · 2024-01-31T12:01:44.000Z

That would mean you didn't add the lines correctly

I copy-pasted them from the troubleshooting guide, double-checked the file and tried with and without tailing newline -- no luck. Do the rules as-is work for you? I am using AppArmor 3.0.4. Also, the file /etc/apparmor.d/usr.bin.firefox didn't exist before, so the copied contents are the only content.

Answer 5 · 2024-01-31T12:18:37.000Z

I'm not 100% sure if the AppArmor settings are different (or even needed?) for Snap. This issue related to the Snap package was recently closed, and the Snap should be updated: #2091

Double check that you are using the latest version.

Answer 6 · 2024-01-31T12:25:31.000Z

Also, the file /etc/apparmor.d/usr.bin.firefox didn't exist before, so the copied contents are the only content.

Then you didn't have apparmor applied to your firefox... delete the file and make sure you have the latest snap version of Firefox.

Answer 7 · 2024-01-31T13:41:04.000Z

Also, the file /etc/apparmor.d/usr.bin.firefox didn't exist before, so the copied contents are the only content.

Then you didn't have apparmor applied to your firefox... delete the file and make sure you have the latest snap version of Firefox.

Thanks, works again ... No idea why sudo snap refresh does in fact not update firefox... Sorry for taking up your time, but thanks for your rapid responses. Closing this issue now.
