Opportunity Workspace for Ubuntu Linux

Installation

1. Open Account > Downloads, then download the DEB package, its SHA-256 checksum, its detached signature, and the public key listed for that version. Save all four files in the same folder.
2. Open Terminal in the folder containing the downloaded files. Confirm that the public-key fingerprint is 8DF5 6C5A C683 ACEE 2E01 C519 FE13 CAA6 0341 9A73.

   gpg --show-keys --with-fingerprint aspectium-desktop-signing-key-2026.asc

3. Convert the public key to a keyring, then verify the package signature. If either command reports an error, do not install the package.

   gpg --batch --dearmor --output aspectium-desktop-signing-key-2026.gpg aspectium-desktop-signing-key-2026.asc

   gpgv --keyring ./aspectium-desktop-signing-key-2026.gpg aspectium-ow__amd64.deb.asc aspectium-ow__amd64.deb

4. Verify the SHA-256 checksum. Continue only if the command reports OK.

   sha256sum --check --strict aspectium-ow__amd64.deb.sha256

5. Install the verified package.

   sudo apt install ./aspectium-ow__amd64.deb

6. Open Account > Billing > Licenses to view or download your license file.

Updates

To update Opportunity Workspace, uninstall the currently installed package first. This does not remove your local Opportunity Workspace data.

sudo apt remove aspectium-opportunity-workspace

Then download, verify, and install the newer DEB package by following the installation steps above.
