Recover from Premature Package Downloads
Successful migration to this release requires that you install all system updates before downloading or installing package updates. Due to dependencies among the updates, failure to observe this rule can make it impossible to install both system updates and package updates. Problem indicators include messages that a system update has failed and package update downloads that never exit the "Downloading" state.
As an admin user with Maglev SSH access privileges, complete the following steps to recover and install the system update.
Using an SSH client, log in to the Cisco DNA Center appliance using the IP address of the out-of-band management network adapter, on port 2222. Use the maglev login command and log in with an admin username and password (which is the same login used for the admin user on the Cisco DNA Center GUI).
At the command line, delete all prematurely downloaded package updates by entering the following command:
Trigger the downloaded system update from the Cisco DNA Center GUI.
After the system update installs successfully, download and install the package updates.
