BAD signature when installing specific package with apk after forced poweroff

Earlier I was playing around with my PinePhone running postmarketOS Edge (based on Alpine Linux Edge) and while installing gcc-go using apk via the command sudo apk add gcc-go the phone froze. As such, I did a forced power off and booted it back up. Now, however, when I do sudo apk add gcc-go it gives me the following output: (1/3) Installing libucontext (0.11-r0) ERROR: libucontext-0.11-r0: BAD signature (2/3) Installing libgo (10.2.0-r5) ERROR: libgo-10.2.0-r5: BAD signature (3/3) Installing gcc-go (10.2.0-r5) ERROR: gcc-go-10.2.0-r5: BAD signature 3 errors; 2567 MiB in 711 packages Go is subsequently then not installed, and when adding any package — including ones that aren't gcc-go — I get the same errors. It does stop if I do sudo apk del gcc-go, but if I subsequently attempt to install gcc-go via the same command as earlier the same error arises. It also persists if I add --no-cache to the install operation. Why is this, and what might I do to resolve it so that gcc-go can be installed?
