** Description changed:

- After upgrading from Ubuntu 24.04 (Noble) to Ubuntu 26.04 (Resolute),
- both `/etc/logrotate.d/cloud-init` (dated September 2024) and
- `/etc/logrotate.d/cloud-init-base` (dated April 2025) are present. Both
- files contain an entry for /var/log/cloud-init*.log, causing logrotate
- to fail with the following errors:
+ After testing upgrading from Ubuntu 24.04 (Noble) to Ubuntu 26.04
+ (Resolute) by running "do-release-upgrade -d", both
+ /etc/logrotate.d/cloud-init (owned by the cloud-init package) and
+ /etc/logrotate.d/cloud-init-base (owned by the cloud-init-base package)
+ are present simultaneously. Both contain an identical entry for
+ /var/log/cloud-init*.log, causing logrotate to fail:
  
  ```
  error: cloud-init-base:1 duplicate log entry for /var/log/cloud-init*.log
  error: found error in file cloud-init-base, skipping
  logrotate.service: Failed with result 'exit-code'.
  ```
  
- The upgrade process should probably remove `/etc/logrotate.d/cloud-init`
- when `cloud-init-base` is installed. Both files are identical and the
- workaround is to manually remove the older `/etc/logrotate.d/cloud-init`
- file.
+ A workaround is to manually remove one of the files.
