Unable to access KBFS on Linux

Hi,

my log id: b3ea3b6e8cf34f724449441c

I'm unable to perform any actions with KBFS using the `keybase` CLI on my Linux machine (openSUSE Tumbleweed)

```shell
$ keybase --version
keybase version 5.5.2
$ keybase fs ls --rec --all /keybase
▶ ERROR EOF
```

I installed `keybase-client` via my system's package manager and enabled the two following system user units. Both systemd services are enabled and seem to be working. I read in a separate story that the "failure" related to kbfs starting up is fine, but I couldn't understand why ([link](https://github.com/keybase/client/issues/18986#issuecomment-523565153))

```
$ systemctl --user status kbfs.service
● kbfs.service - Keybase Filesystem service

I appreciate any help you can offer, and I'm happy to share anything else you might need

Start by reproducing `keybase fs ls --rec --all /keybase` on openSUSE Tumbleweed and inspect the `keybase.service` and `kbfs.service` user-unit logs. Use the reported log ID and service status to identify why the CLI returns EOF; done means KBFS actions through the CLI work without that error.
