# 就地套用安全性更新
如需套用更新的概觀，請參閱 [使用 DNF 和儲存庫版本套用安全更新](managing-repos-os-updates.md#apply-security-updates)。的 `--security`選項`dnf upgrade`會將套件更新限制為只有具有 諮詢的套件更新。本節的其餘部分將介紹如何僅安裝特定安全性更新。
**注意**
建議套用新 AL2023 版本中提供*的所有*更新。僅選擇安全性更新，或僅選擇特定更新應該是例外狀況，而不是規則。
## 套用諮詢中提到的更新
輸出第一欄的諮詢識別符`dnf upgradeinfo`可用來套用諮詢中提及之套件的更新。您可以指示`dnf`套件管理員將諮詢中的套件更新為最新的可用套件，或更新至諮詢中提及的版本。如果已安裝更新，則更新命令為無操作。
若要僅將受影響套件*的更新套用到諮詢中提到的版本*，請使用 `dnf upgrade-minimal`命令，同時使用 `--advisory`選項來指定諮詢。下列範例在 AL2023 版本 2023`dnf upgrade-minimal`.0. 容器中執行。 [20230315](https://docs.aws.amazon.com/linux/al2023/release-notes/relnotes-2023.0.20230315.html)

即使`--releasever=latest`當請求是 `dnf`執行解決諮詢*所需的最低更新*時，相同的套件版本也會更新。
搭配 `--advisory`選項使用一般`dnf upgrade`命令，會將諮詢中提到的相關套件更新為可用的*最新版本*，可能比諮詢中提到的版本更新。
**注意**
除非`system-release`套件已更新，否則`dnf`鎖定為 的 AL2023 儲存庫版本*不會變更*。
**警告**
從不同 AL2023 版本安裝更新時，如果未變更`dnf`鎖定的儲存庫版本，*則必須*注意任何後續的變動`dnf`操作。例如，安裝或更新套件時，由於較新版本中的套件相依性可能已變更，因此您保留的較舊版本可能無法滿足這些新的相依性。
下列範例是在 AL2023 版本 [2023.0.20230315](https://docs.aws.amazon.com/linux/al2023/release-notes/relnotes-2023.0.20230315.html) 容器中執行，此容器中參照 AL2023 的最新版本，其寫入時間為 [2023.5.20240708。](https://docs.aws.amazon.com/linux/al2023/release-notes/relnotes-2023.5.20240708.html)請注意，`curl`更新至 的兩個版本都比`update-minimal`更新至的版本更新，但此更新版本帶來新的相依性。
