When trying to update my primary PGP key I encountered an error through the Chrome browser extension. I used my proper key + passphrase (copy-pasted from a password manager to reduce errors) and had to open console a there was no indication that it passed or failed.

Key was exported using the following command:

`gpg --output private.pgp --armor --export-secret-key 'martin.lowe@eclipse-foundation.org'`

JS console stack:

I don't think I'm using the extension wrong, so this seems to be an issue extension side. 

Some additional info since you might need it:

Browser: Chromium - Version 83.0.4103.97 (Official Build) Arch Linux (64-bit)
OS: Manjaro, kernel 5.6.16-1-MANJARO (up-to date with rolling release stable)
Extension version: 7.7.9

In my own case, I can update a key just fine using that interface. I'm not sure what's going wrong for this user.

These issues are very hard to debug because it would be super helpful to have the actual key that causes the issue. But that is not possible, it's a private key. Once in a while I succeed in having the user create another similar key that also causes the same issue, which really helps.

But maybe it can be fixed using the stack alone (without a test).
