Collabora Online 25.04.2.3

Released on 19 June 2025.

• Major release of Collabora Online. Please find all details in the 25.04 announcement.
• We have updated our PGP signing key for COOL and CODE .rpm and .deb packages to align with modern standards. This change is necessary as some recent Linux distributions have migrated to Sequoia-PGP for key and signature verification.
  • Action required:
    Users will need to update the Collabora Online PGP key on their systems. This can be done using the following commands:
    • On RPM based distros:
      wget -O repomd.xml.key https://collaboraoffice.com/repos/CollaboraOnline/CODE-rpm/repodata/repomd.xml.key && sudo rpm --import repomd.xml.key
    • On DEB based distros:
      cd /usr/share/keyrings && sudo wget -O collaboraonline-release-keyring.gpg https://collaboraoffice.com/downloads/gpg/collaboraonline-release-keyring.gpg
