Description

Test the apertis-update-manager automatic update via mass storage device.

Resources

  • A static update bundle file of the same architecture, variant and version as the testing image
  • A Fat32 USB flash drive, preloaded with the update bundle at the root of the disk
  • The latest static update file can be downloaded at the same location than the target image. It has the same basename, and a '.delta' extension
  • The static update file should be copied to the flash drive using the name 'static-update.bundle'.
  • A PC must be connected to DUT serial port

Execution Steps

  1. Check the initial deployment
    2. $ sudo ostree admin status
  2. Prepare the copy of commit and deploy to allow the upgrade to the same version
  3. Command below shows you an initial commit ID, for instance
    4. $ export BOOTID=$(sudo ostree admin status | sed -n -e 's/^\* apertis \([0-9a-f]*\)\.[0-9]$/\1/p'); echo $BOOTID
  4. Get the Collection ID and ref
    5. $ export CID=$(sudo ostree refs -c | head -n 1 | tr -d '(),' | cut -f 1 -d ' '); echo COLLECTION_ID=$CID
    $ export REF=$(sudo ostree refs -c | head -n 1 | tr -d '(),' | cut -f 2 -d ' '); echo REF=$REF
  5. Create the list of files to skip and enshure there are some files in these directories
    6. $ ls -1d /usr/share/locale /usr/share/man /usr/share/zoneinfo > /tmp/skip
    $ du -sh /usr/share/locale /usr/share/man /usr/share/zoneinfo
  6. Create the commit with changed timestamp and skipped list from above to allow upgrade with recent update file
    7. $ export NEWID=$(sudo ostree commit --orphan --tree=ref=$BOOTID --add-metadata-string=ostree.collection-binding=$CID --bind-ref=$REF --timestamp="1 year ago" --skip-list=/tmp/skip); echo "New commit: $NEWID"
  7. Deploy the prepared commit
    8. $ sudo ostree admin upgrade --allow-downgrade --deploy-only --override-commit=$NEWID --reboot
  8. Wait until the system is booted again and check the deployment
    9. $ sudo ostree admin status
  9. The booted commit (started with '*') must have ID which we prepare and the initial commit ID should be marked as '(rollback)'
  10. Check booted deployment have no file objects which we skip
    11. $ du -sh /usr/share/locale /usr/share/man /usr/share/zoneinfo
  11. Remove the initial deployment
    12. $ sudo ostree admin undeploy 1
  12. Reboot the system
  13. Plug the USB flash drive in the device
  14. The update starts automatically
  15. After the update, the device will reboot automatically
  16. Remove the USB flash drive immediatly after reboot
  17. Check the current deployment has been updated and that the rollback entry points to the prepared deployment
    18. $ sudo ostree admin status

Expected

The update was properly applied
