當我在 Ubunutu 22.04 中執行軟體更新程式時，它在 /boot 錯誤中給出磁碟空間不足並且無法更新。當我運行 sudo apt Upgrade（在 sudo apt update 之後）時，我收到可能丟失韌體、寫入錯誤和處理包錯誤的警告。我檢查了這些韌體檔案是否丟失，但它們位於該目錄中。
我檢查了askubuntu上的其他答案，我能找到的最常見原因是安裝了很多內核，我只安裝了三個（包括正在使用的）。我遵循了答案在此askubuntu頁面上並嘗試使用sudo apt autoremovewhich 給出與 相同的錯誤sudo apt upgrade。我還嘗試安裝 ubuntu-tweaks 但它指出它沒有發布文件並且無法找到套件（添加存儲庫後）。
我不想刪除其他內核，因為我曾經遇到過一個早期問題，當時我的系統在更新後無法使用最新的內核啟動，而是在較舊的內核上啟動。我還使用 LUKS 來加密我的硬碟，因此據我了解我需要一個單獨的啟動分割區。我的 /boot 分割區大小為 500mb，根據磁碟有 25mb 可用空間，儘管系統更新程式在錯誤中表示 0 位元組可用。
誰能推薦解決此問題的最佳方法？我是否必須刪除其他內核，或者我可以安全地調整啟動分割區的大小嗎？
升級的輸出、自動刪除命令和安裝的核心清單如下，目前正在使用 5.15.0-37-generic。
