I had a complicated upgrade t0 6.5.1 because the post install script in the debian package was failing. I unmounted and removed the directory, rerun the script and it got created back. The post installation process seems to be running fine now, but after restarting, I can't access the /keybase directory or access my files in KBFS.
$ keybase version
