I see 3 workarounds
1) create a symlink from dkms.key to mok.priv and dkms.der to mok.der.
2) Create a separate dkms.key. Not so convenient to have 2 keys
though (though I could just stop using mok.der)
3) Comment out sign_tool in /etc/dkms/framework.conf, and sign
manually. A little inelegant for dkms, but otherwise easy.
1) or 3) would seem simplest to do, but strangely neither of them
fixes the final problem. Still gives the same error, "DKMS tree
already contains: nvidia-current-470.86. You cannot add the same
module/version combo more than once."
Not sure if it would work after nvidia purge/reinstall. Or if it needs
a reboot.
This error is pervasive.
I've reconfigured to follow the dkms instructions at
/usr/share/doc/dkms/README.md.gz, just using /root/dkms.key and
dkms.der. Generated the keys afresh and registered them. Manually
deleted any nvidia-current*ko files under /lib/modules/*. Rebooted.
Purged nvidia-kernel-dkms. Rebooted again.
But the error comes back. Even after deleting, purging, rebooting, when
I then install nvidia-kernel-dkms anew, I still get the same error
message:
