Provided python3-dnf-plugin-multisig is installed, a signature verification is enabled for given repository and a package being correctly signed with the keys: Installing that package which have a single signature and the signature algorithm is disabled in global crypto policy will cause DNF to reject that package. *Installing that package which have multiple signatures and some of the algorithms are enabled and some are disabled will let DNF to accept that package.

`multisig` no longer fails to install packages that use both supported and unsupported RPMv6 signing algorithms:: Before this update, you could not install packages with signatures that used both supported and unsupported RPMv6 package signing algorithms. As a consequence, DNF rejected such packages when verifying their signatures because of the unsupported algorithms. With this update, the DNF `multisig` plugin ignores signatures classified as `NOTTRUSTED` in the `rpmkeys` command output. As a result, `multisig` can install packages that use both supported and unsupported signing algorithms.
