SHA1SUMS Kali Linux

I followed the guide on how to verify signatures in kali, the end result i'm getting after issuing the verify command is

"

gpg: can't open 'SHA1SUMS.gpg'

gpg: verify signatures failed: file open error'

i followed the steps exactly the way they are shown in the kali website. Does this mean i should get a new one as it can't be verified? because i never got good signature response
