[kenhys]

Thanks, I've fixed them.

[kenhys]

TODO: try Provides: also works as expected. It should be handled by another PR.

[kenhys]

If it removes the transitional package entry and use Provides:, it can't be upgraded even if you point to v5.

Before (transitional):

• even though rewriting fluentd.sources, you can upgrade to fluent-apt-source with apt upgrade.
• fluentd-apt-source will removed(not purged), you must manually purge if you want

After (no transitional, use provides)

• even though rewriting fluentd.sources, you can't upgrade to fluent-apt-source with apt upgrade. (must install manually with apt install -y ...)
• fluentd-apt-source will be removed (not purged, so you must purge manually if you want)

[kenhys]

As the former behavior is preferred, so stay as is.

Thanks for your check! Understood!
