Help with upgrade please

Hi and downloaded the installer and verify signature when I recently launched Bisq. It syas I have to upgrade to version 1.19.19. I followed the steps in the wiki on verifying signature but get errors below. any suggestions please.

todd@Live5D:~/Downloads$ gpg --digest -algo SHA256 --verify 4A133008.asc
gpg: Note: ‘–verify’ is not considered an option
gpg: selected digest algorithm is invalid
todd@Live5D:~/Downloads$ gpg --digest -algo SHA256 --verify E222AA02.asc
gpg: Note: ‘–verify’ is not considered an option
gpg: selected digest algorithm is invalid

What I do is having .deb and .deb.asc file in the same directory (Downloads), so cd Downloads and gpg --verify Bisqfile.deb.asc

thankyou. i receive this:

todd@Live5D:~/Downloads$ gpg --verify Bisq-64bit-1.9.19.deb.asc
gpg: assuming signed data in ‘Bisq-64bit-1.9.19.deb’
gpg: Signature made Mon 03 Feb 2025 05:07:47 PM CST
gpg: using RSA key B493319106CC3D1F252E19CBF806F422E222AA02
gpg: Good signature from “Alejandro García alejandro.garcia@disroot.org” [expired]
gpg: Note: This key has expired!
Primary key fingerprint: B493 3191 06CC 3D1F 252E 19CB F806 F422 E222 AA02

That’s enough, it means that it has been signed by this key, but it has not a good web of trust (it has not been signed by keys you trust, which is normal for occasional gpg users).
