ErrorCode::kDownloadMetadataSignatureMismatch when trying to sideload

[xerz-one]

Using LineageOS Recovery version 17.1 (20201225) on my Xperia XZ2 Compact, when trying to install LineageOS for microG I get the following error:

Error applying update: 26 (ErrorCode::kDownloadMetadataSignatureMismatch)
E:Error in /sideload/package.zip (status 1)

I found a few instances of people finding this issue, but no one actually solving it:

After further searching, this workaround did the trick for me! This isn't enough to close the ticket imho, but at the very least it gets the job done lineageos4microg/docker-lineage-cicd#105 (comment)
