I thought I close this after the release of 2.2.18.
Anway, it's done, so, closing.

We use "error ..." and "failed to ..." interchangable. The German translation even uses the same term for both.
Thus I think it would be better to keep the old diagnostic but show it only in --verbose mode.

This should be normal priority as we continue to receive bug reports about UIServer and the usage in GpgEX of the UIServer protocol keeps us from removing it in Kleopatra.

I did not want to move the fingerprint verification process more prominent with an entry field or something like that.

With the new version we get an even more extensive rework of the certify dialog. We now also have support for search tags.

It's probably a wrong encoding in the italian translation. Will be fixed with updating our build system to buster and NSIS-3

I removed it. Looks dead to me.

Is this resolved?

I tuned down the error message. I don't think there is a problem here anymore.

To clarify this for someone other then me:

After T4747 and T4748 are fixed this needs to be added to the installer, but sending Windowmessages is at least easy for NSIS. From the MSI installer this will be more difficult.
