Hello there,
the issue is clearly described in the output. All you have to do is look it up.

You have added the repository, but you did not import the signing key.
Just follow the official instructions.

Hi did already but same it happen in latest version it was working on version 9 …

mkdir -p -m 700 ~/.gnupg
curl -fsSL https://download.onlyoffice.com/GPG-KEY-ONLYOFFICE | gpg --no-default-keyring --keyring gnupg-ring:/tmp/onlyoffice.gpg --import
chmod 644 /tmp/onlyoffice.gpg
sudo chown root:root /tmp/onlyoffice.gpg
sudo mv /tmp/onlyoffice.gpg /usr/share/keyrings/onlyoffice.gpg

Hello there,
apparently onlyoffice did not sign their own keys? To circumvent this you can edit the source file and add [trusted=yes]. It should look like this (file under /etc/apt/sources.list.d/onlyoffice.list):

deb [trusted=yes signed-by=/usr/share/keyrings/onlyoffice.gpg] https://download.onlyoffice.com/repo/debian squeeze main
