do-release-upgrade on Ubuntu 18.04 is blocked

I’m trying to move my device from Ubuntu 18.04.6 LTS to 20.04. The first sudo do-release-upgrade was interrupted when my Internet died. Ever since, re-running it stops with “Please install all available updates for your release before upgrading.” **Environment** * Board: NVIDIA Jetson Nano * Current OS: Ubuntu 18.04.6 LTS (bionic) **What I tried** 1. Ran sudo do-release-upgrade, but cancelled midway due to internet issues. 2. Re-ran the command → “Please install all available updates for your release before upgrading.” 3. Tried to bring the system fully up to date: ```bash sudo apt update sudo apt full-upgrade -y Output ends with: 0 upgraded, 0 newly installed, 0 to remove and 1965 not upgraded. **Question** How can I remove the already downloaded updates and any partial upgrade state left by the cancelled run?
