Since the package installation failed, you can just resume that with
dpkg --configure --pending

Otherwise, you can also invoke dkms manually:

dkms build nvidia-legacy-340xx/340.108 [--force] [-k 6.1.0-3-amd64]
dkms install nvidia-legacy-340xx/340.108 [--force] [-k 6.1.0-3-amd64]
dkms status nvidia-legacy-340xx/340.108 [-k 6.1.0-3-amd64]

The kernel flag (-k ..., please use the correct kernel for your machine, 
the current kernel in sid would be 6.1.0-3-amd64) is optional if you 
just want to target the running kernel version (that would be what 
'uname -r' outputs).
