Problem: armbian-base-files artifact for jammy fails to build because
apt_find_upstream_package_version_and_download_url() looks for 'jammy-updates'
in https://github.armbian.com/base-files.json, but only 'jammy' key exists.
Root cause:
- For Ubuntu LTS (focal, jammy), code sets package_download_release to '${RELEASE}-updates'
- JSON file from github.armbian.com only has base release keys (jammy, noble, etc)
- jq query returns null for 'jammy-updates'
- Artifact excluded from build matrix after 10 retries
Solution: Add fallback logic
- First try with '-updates' suffix (jammy-updates)
- If not found and release ends with '-updates', retry with base release (jammy)
- This allows using base release data when -updates is not available
Impact:
- Fixes jammy base-files artifact build
- Allows jammy images to build (they depend on this artifact)
- Maintains preference for -updates when available
- No impact on other releases (Debian, non-LTS Ubuntu)
- otherwise, when the lookup at "jammy-updates" fails (due to server instability), and "jammy" works, we end up with the wrong version
- non-LTS releases don't have the "-updates" repo, so don't even try, which should make everything faster
- TODO: yet-another opportunity to have a release metadata file, otherwise this is yet-another place where we list "jammy"
- bsp-cli: now depends on `base-files (>= ${REVISION})`, this way upgrading the bsp-cli causes our base-files to be installed
- bsp-cli no longer does gymnastics with /etc/os-release et al, all done in armbian-base-files now
- general/apt-utils.sh: introduce `apt_find_upstream_package_version_and_download_url()`
- base-files: add release to version, in order to comply with repo restrictions (valid repos can't have two different debs with same name and version, md5 must match)
