制御プロセスがエラーコードで終了したため、snapd.seeded.serviceのジョブが失敗しました

今朝snapdを2.32.3.2から2.32.9に更新した後、次のエラー出力を受け取りました。

Job for snapd.seeded.service failed because the control process exited with error code. 
See "systemctl status snapd.seeded.service" and "journalctl -xe"      
for details. snapd.seeded.service couldn't start.
snapd.snap-repair.service is a disabled or a static unit, not starting it.

「systemctl status snapd.seeded.serviceの出力：

Journalctl -xeを見ると何も表示されませんが、実行するのを待ちましたか？ただし、これはその時間枠のsyslog出力です。

質問は、「snapd.seeded.service」が何をするものであり、なぜ失敗したのですか？スナップの実行に影響しますか？

このコマンドで問題を修正できます：

$ Sudo snap install hello-world

snapd.seeded.serviceをもう一度開始します。

$ systemctl start snapd.seeded.service

snapd.seeded.serviceが実行されているかどうかを確認します。

$ systemctl status snapd.seeded.service

AskUbuntuに関する次の質問が役立つ場合があります。 snapd.seeded.serviceはアップグレード時に開始できませんでした
