Client: Keybase won't run after install - Linux Mint 18.3

[NginUS]

$ run_keybase
▶ WARNING Permission denied opening config file /home/username/.config/keybase/config.json
▶ WARNING Permission denied opening gui config file /home/username/.config/keybase/gui_config.json
▶ WARNING Permission denied opening updater config file /home/username/.config/keybase/updater.json
▶ ERROR open /home/username/.config/keybase/keybase.autogen.env: permission denied

I saw a similar issue here & made sure I did own ~/.config, so their fix doesn't apply.

Are you sure permissions are correct, recursively? What if you do

sudo chown -R $(whoami):$(whoami) ~/.config/keybase

@heronhaye
That did it- thanks!

[heronhaye]

Thanks. Do you know how the permissions might have gotten messed up? Did you run any keybase commands with sudo, perhaps?

As per the published instructions here:
https://keybase.io/docs/the_app/install_linux

I ran the sudo apt etc. but that shouldn't have done anything...

Exactly the same steps I did and the same symptoms but on kubuntu 19.04. Also the chown above fixed it.
