Cannot get into KBFS

[ghost]

So for a while now I have not been able to get into my KBFS files. I've tried uninstalling and reinstalling, logging out and logging back in again, to no avail.

I am on Arch Linux.

I see this in your logs:

30491 2018-04-14T17:41:14.757616-05:00 ▶ [DEBU kbfs start.go:37] 064 Mounting: "/run/user/1000/keybase/kbfs"

For some reason your user (UID=1000) doesn't have permissions to mount /run/user/1000/keybase/kbfs. I would guess either that user is not part of the fuse group on your machine, or somehow the permissions for /run/user/1000/keybase/kbfs were messed up.

Alright, that makes sense, kind of. How would I go about adding those permissions?

What is the output of these two commands?

ls -ld /run/user/1000/keybase/kbfs
groups

Does the command usermod -aG fuse taxborn help at all? I'm not sure if this is a requirement on arch or not.

[ghost]

It simply tells me this message: usermod: group 'fuse' does not exist

[strib]

What does this command say:

ls -l `which fusermount`

[ghost]

[strib]

Ah, that seems to be the problem. Usually fusermount's permissions are -rwsr-xr-x (note the "s" suid bit). Somehow that got changed on your system. Try sudo chmod u+s /usr/bin/fusermount and see if run_keybase will work correctly after that.

That seems to fix it! Thank you for your help.
