Unable to update `core` module to 15.0.12.55 - sha1 did not match

I was running updates with `fwconsole ma upgradeall` from the console, and I'm seemingly unable to ugprade the `core` module:

1163434/1163584 [===========================>] 99%The following error(s) occured:
- File Integrity failed for /var/www/html/admin/modules/_cache/core-15.0.12.55.tgz.gpg - aborting (sha1 did not match){noformat}

 

 

I checked the signature of the file in question and the GPG key matches.  I looked inside the archive as well, and saw that there was a `module.sig` inside the archive with sha256sums of the module contents (which was itself correctly signed with the same key as the archive as a whole).  I'm not sure where in the world that sha1sum is happening, even.

Let me know if I can provide any more info!
