在我的系統中,我想出了以下 bash 別名:
alias updt='apt update -y && apt update -y && apt autoremove -y'
我幾乎每次使用系統時都會運行這個。我的問題是:
是否可以讓系統在每次關閉電腦時都執行此命令?
作為獎勵:我可以像在 Windows 上一樣,在直接從桌面環境的右上角使用關閉選項時使系統自動更新嗎?

是的。這是一個設定。
易於已經後台 apt 更新和 apt 升級嗎...
/lib/systemd/system/apt-daily.timer // update
/lib/systemd/system/apt-daily-upgrade.timer // upgrade
....您真正需要做的就是遠離它,並如下所示調整設定。
編輯設定檔
/etc/apt/apt.conf.d/50unattended-upgrades
:
命令範例:$ sudo nano /etc/apt/apt.conf.d/50unattended-upgrades
第 1 步:編輯您的來源。預設設定僅包括 -security 儲存庫。您可以更新它以包含您的所有來源。最佳實踐是添加穩定、可靠的來源,例如-updates 和-security(這兩個應該是升級的絕大多數!)不建議將其用於-提議的或其他測試/不穩定的來源。
// Automatically upgrade packages from these (origin:archive) pairs
//
// Note that in Ubuntu security updates may pull in new dependencies
// from non-security sources (e.g. chromium). By allowing the release
// pocket these get automatically pulled in.
Unattended-Upgrade::Allowed-Origins {
"${distro_id}:${distro_codename}";
"${distro_id}:${distro_codename}-security";
// Extended Security Maintenance; does not necessarily exist for
// every release and this system may not have it installed, but if
// available, the policy for updates is such that unattended-upgrades
// should also install from here by default.
"${distro_id}ESM:${distro_codename}";
"${distro_id}:${distro_codename}-updates";
// "${distro_id}:${distro_codename}-proposed";
// "${distro_id}:${distro_codename}-backports";
};
第 2 步:啟用自動刪除。只需取消最後一行的註解:
// Do automatic removal of unused packages after the upgrade
// (equivalent to apt-get autoremove)
//Unattended-Upgrade::Remove-Unused-Dependencies "true";
步驟 3:關機時進行升級而不是在後台。只需取消最後一行的註解:
// Install all unattended-upgrades when the machine is shutting down
// instead of doing it in the background while the machine is running
// This will (obviously) make shutdown slower
//Unattended-Upgrade::InstallOnShutdown "true";
