No need to use old path for fluent-package.

Need to rebase with #499

[kenhys]

failure on focal and jammy. checking....

[kenhys]

Hmm, postinst hook may not work as expected 🤔

[daipom]

It sometimes fails in other PRs as well. (#501)

Is it possible that #489 (comment) problem still remains?

There is a possibility of it. checking...

On local VM, update-from-v4.sh will succeed. 🤔

[kenhys]

Try to run the failed job again.

I'm doubt that this fragile behavior comes from running systemctl immediately. (The state of current status is not synced yet)
maybe waiting appropriate time will work. 🤔

I wonder if this is the real cause of this problem.

I have tested the following 2 patterns on my local.

• Add sleep 3 before systemctl status check like this PR.
• Add --wait option to systemctl status check.

However, both patterns fail about 1 in 3 times.

It may be a good idea to add sleep or --wait option just in case, but perhaps it has nothing to do with this problem.

I reran tests several times and confirmed they can still fail.
However, I think it has nothing to do with this PR.

This PR looks good to me.

Thank you for checking.
I'll investigate it again.

Anyway, using --wait option is better, I'll fix it.

changed to use --wait option to sync.
