"Agent connection failed" message on start and "Add to agent"

[mackushev]

Expected Behavior

I'm trying to add key from KeepassXC
Key added and checkbox 'Add key to agent then database is unlocked ' is set
I expect than key became visible in ssh-agent -L

Current Behavior

Then keepass starts it shows "Agent connection failed"
Button "Add to agent" shows the same message

Possible Solution

Steps to Reproduce

1. Add key to keepass
2. Set 'Add key to agent then database is unlocked ' on
3. Exit keepass and start it again

Context

ssh-agent don't crash on "add to agent" or "remove from agent" buttons like at #1746

You cannot use ssh agent with the snap distribution due to sandboxing.

I also ran into this problem. And I solved it by installing the Ubuntu package, not the snap distribution.

You can download the default ubuntu package, but it's outdated (2.4.3, 2019). To install a more recent version follow the instructions on this blog-article: https://keepassxc.org/blog/2017-10-25-ubuntu-ppa/

@droidmonkey
Just for the record, IIUC, there is a snap-approved solution to this: make the snap run its own ssh-agent instead of connecting to the global one
See here for a discussion

Now, whether it is worth implementing that solution in KPXC or not, I have no idea, but there seems to be a way a least

That is not a solution. No other app can benefit from using an agent within your snap environment.
