假设^(Suppose)OTA（无线^{(Over-the-Air)}）iPadOS更新失败并出现“无法安装更新”错误。在这种情况下，您很可能会在所有后续尝试中反复出现“软件更新^{(Software Update)}失败：下载 iPadOS 时出错”弹出窗口。为什么会这样？

iPad重复显示“软件更新^{(Software Update)}失败”错误的原因有很多。例如，它可能是系统软件更新文件损坏、内部存储空间不足或网络配置损坏。本故障排除教程将演示如何修复 iPad 的“软件更新^{(Software Update)}失败”错误。

删除^(Delete)部分下载^{(Partially Downloaded Update File)}的更新文件

iPad 上出现“无法安装更新”和“软件更新失败”错误的最可能原因是损坏的软件下载文件阻止您恢复 iPadOS 更新。因此^(Hence)，修复错误的最佳方法是删除并从头开始重新下载。要做到这一点：

1. 打开iPad 上 的“设置”应用。^(Settings)
2. 点击通用。
3. 点击 iPad 存储。
4. 向下滚动^(Scroll)并点击软件更新^{(Software Update)}列表。
5. 点击删除更新^{(Tap Delete Update)}，然后再次确认。

您现在可以返回Settings > General > Software Update > Download并安装^(Install)”以重新下载 iPadOS 更新。

注意：在每个后续修复之前或之后重复^(Repeat)上面的步骤 1-5。

关闭并重新启动您的 iPad

如果删除软件更新文件后 iPadOS 更新错误继续弹出，最好在下次尝试之前重新启动 iPad。要重启任何 iPadOS 设备：

1. 打开“设置”^(Settings)应用程序，然后点按“General > Shutdown” 。
2. ^(Swipe)在“滑动关机”屏幕上向右滑动^(Off)。

1. 等待 30 秒并按住Power/Top按钮，直到您看到Apple标志。

强制重启你的 iPad

如果 iPadOS 死机并显示“软件更新失败：下载 iPadOS 时出错”弹出窗口，并且所有触摸手势均无响应，则您必须强制重启 iPad。

^{(Force-Restart)}在没有主页按钮的情况下^{(Home Button)}强制重启iPad

依次按下并释放音量调高按钮和音量调低^(Down)按钮。然后，快速按住顶部^(Top)按钮 15-20 秒，然后在看到Apple标志时松开。

使用主页按钮^{(Home Button)}强制重启 iPad

同时按住主页^(Home)和顶部^(Top)按钮 15-20 秒，直到看到Apple标志。

释放 iPad 上的存储空间

如果您的 iPad 剩余存储空间很少，也可能会出现 iPadOS 更新错误。要回收平板电脑上的空间：

1. 打开“设置”应用。
2. 前往“通用”>“iPad 存储空间”。
3. 查看“建议^{(Recommendations)}”部分以了解释放空间的快速方法——例如，删除电视节目、卸载未使用的应用程序、将照片存储在 iCloud 中等。或者，向下滚动并卸载 iPad 上的非必要应用程序^{(uninstall non-essential apps on your iPad)}。

检查 Apple 服务器状态

如果“软件更新失败”错误继续出现在您的 iPad 上，则可能与 Apple 的下载服务器有关。要进行检查，请访问Apple 系统状态页面^{(Apple System Status page)}。如果任何服务器出现故障，请等到它们恢复在线后再重试。

此外，如果您在 iPadOS 发布后立即尝试进行主要的iPadOS 版本^{(iPadOS version)}升级（例如 iPadOS 16.0），您可能想在几个小时后重试。这样一来，您就可以避免其他 iPadOS 用户最初的更新请求，并防止服务器出现错误和速度减慢。

解决^{(Troubleshoot Your)}iPad 的网络连接问题^{(Network Connection)}

“软件更新失败”iPadOS 下载错误可能与您的互联网连接有关。尝试以下修复并检查是否有帮助：

• 打开“设置”^(Settings)应用程序，打开然后关闭飞行模式^{(Airplane Mode)}开关，以消除Wi-Fi和蜂窝网络的小故障。
• 重启或重置Wi-Fi路由器^{(reset the Wi-Fi router)}，解决路由器端问题。
• 前往Settings > Wi-Fi并连接到其他 Wi-Fi 路由器。
• 禁用Wi-Fi并使用蜂窝数据。在数 GB 的更新期间，您可能会产生额外的运营商费用。

重置 iPad 的网络设置

重置 iPad 上的网络设置，以排除由损坏的 Wi-Fi 或蜂窝网络配置引起的 iPadOS 更新错误。要做到这一点：

1. 打开iPad 上 的“设置”应用。^(Settings)
2. 前往“General > Reset > Transfer”或“还原^(Reset)iPhone”。
3. 点击重置网络设置。

1. 输入您的设备密码和屏幕时间^{(Screen Time)}密码（如果屏幕时间^{(Screen Time)}处于活动状态）。
2. 点击重置以确认。

如果这没有帮助，请改为执行所有设置重置。为此，请重置上述步骤，但在第 3 步中选择重置所有设置^{(Reset All Settings)}。

网络设置或所有设置重置会擦除 iPad 上保存的 Wi-Fi 网络和密码。之后手动^(Manually)加入 Wi-Fi 热点或使用蜂窝数据。

^(Perform)通过Finder或 iTunes 执行iPadOS更新^(Update)

如果无线^{(Over-the-Air)}更新在您的 iPad 上反复失败，您必须通过Mac上的^(Mac)Finder应用程序更新设备。如果使用 PC，则必须使用 iTunes；如果您还没有 iTunes，请通过 Microsoft Store 下载 iTunes 。^{(download iTunes via the Microsoft Store)}

1. 通过USB^(USB)将 iPad 连接到 macOS 或Windows计算机。
2. 在访^(Finder)达或 iTunes 中选择您的 iPadOS 设备。
3. 解锁^(Unlock)您的 iPad，然后轻点“允许^(Allow)”或“信任^(Trust)”（如果您之前没有将它连接到同一台计算机）。
4. 选择^{(Select Back Up)}立即备份以备份您的数据（可选）。
5. 选择检查^(Check)更新或立即更新^(Update)按钮^(Updates)。

1. 选择下载^{(Select Download)}和更新^(Update)并同意^(Agree)软件更新许可条款。
2. 等待^(Wait)Finder或 iTunes从Apple服务器下载最新版本的IPSW（iPhone 软件）格式的设备软件和固件^{(device software and firmware in IPSW (iPhone Software) format)}。然后它将自动执行更新。请勿同时断开您的 iPad。

或者，您可以通过 IPSW.me 手动下载最新版本的iPadOS^(IPSW.me)。然后，按住Option/Alt键并选择“检查^(Check)更新”或“立即更新^(Update)”^(Updates)按钮（在第 5 步中），然后从计算机的“下载”文件夹中选择^(Downloads)IPSW文件。

^{(Software Update)}修复^(Fixed)了 iPad 上的软件更新失败错误^(Error)

iPad 上的“软件更新^{(Software Update)}失败”是一个可以直接修复的错误；删除下载的更新文件、执行设备重启和释放存储空间几乎总能奏效。如果没有，请完成其他修复，你应该很快就能在你的 iPad 上运行最新版本的 iPadOS。

How to Fix “Software Update Failed: An Error Occurred Downloading iPadOS” on iPad

Suppose an OTΑ (Over-the-Air) iPadOS update fails with an “Unable to Install Update” error. In that case, the chances are you’ll run into a recurring “Ѕoftware Update Failed: An error occurred downloading iPadOS” pop-up in all subsequent attemрts. Why doеs that hapрen?

There are many reasons why your iPad displays a “Software Update Failed” error on repeat. For example, it could be a corrupt system software update file, a lack of sufficient internal storage, or a broken network configuration. This troubleshooting tutorial will demonstrate how to fix the iPad “Software Update Failed” error.

Delete the Partially Downloaded Update File

The most likely cause behind the “Unable to Install Update” and “Software Update Failed” errors on the iPad is when a corrupt software download file prevents you from resuming an iPadOS update. Hence, the best way to fix the error is to delete and perform a fresh download from scratch. To do that:

1. Open the Settings app on your iPad.
2. Tap General.
3. Tap iPad Storage.
4. Scroll down and tap the Software Update listing.
5. Tap Delete Update, and then again to confirm.

You can now go back to Settings > General > Software Update > Download and Install to re-download the iPadOS update.

Note: Repeat steps 1–5 above before or after each subsequent fix.

Shut Down and Restart Your iPad

If the iPadOS update error continues to pop up despite deleting the software update file, it’s a good idea to restart your iPad before your next attempt. To reboot any iPadOS device:

1. Open the Settings app and tap General > Shutdown.
2. Swipe right on the Slide to Power Off screen.

1. Wait 30 seconds and hold the Power/Top button until you see the Apple logo.

Force-Restart Your iPad

If iPadOS freezes with the “Software Update Failed: An error occurred downloading iPadOS” pop-up and all touch gestures are unresponsive, you must force-restart your iPad.

Force-Restart iPad Without a Home Button

Press and release the Volume Up button and the Volume Down button one after the other. Then, quickly hold the Top button for 15-20 seconds and release it when you see the Apple logo.

Force-Restart iPad With a Home Button

Hold the Home and Top buttons simultaneously for 15-20 seconds until you see the Apple logo.

Free Up Storage Space on Your iPad

iPadOS update errors can also appear if your iPad only has little remaining storage. To reclaim space on your tablet device:

1. Open the Settings app.
2. Go to General > iPad Storage.
3. Check the Recommendations section for quick ways to free up space—e.g., delete TV shows, offload unused apps, store photos in iCloud, etc. Or, scroll down and uninstall non-essential apps on your iPad.

Check the Apple Server Status

If the “Software Update Failed” error continues to crop up on your iPad, it could be something to do with Apple’s download servers. To check, visit the Apple System Status page. If any servers appear down, wait until they come back online before you retry.

Also, if you’re attempting a major iPadOS version upgrade—e.g., iPadOS 16.0—immediately after its release, you might want to try again after a few hours. That way, you can avoid the initial rush of update requests from other iPadOS users and prevent server errors and slowdowns.

Troubleshoot Your iPad’s Network Connection

The “Software Update Failed” iPadOS download error may be related to your internet connection. Try the following fixes and check if that helps:

• Open the Settings app, turn the Airplane Mode switch on and then off to eliminate minor glitches with Wi-Fi and cellular.
• Restart or reset the Wi-Fi router to resolve problems on the router side.
• Go to Settings > Wi-Fi and connect to a different Wi-Fi router.
• Disable Wi-Fi and use cellular data. You may incur additional carrier charges during multi-gigabyte updates.

Reset Your iPad’s Network Settings

Reset the network settings on your iPad to rule out iPadOS update errors that stem from a corrupt Wi-Fi or cellular configuration. To do that:

1. Open the Settings app on your iPad.
2. Go to General > Reset > Transfer or Reset iPhone.
3. Tap Reset Network Settings.

1. Enter your device passcode and the Screen Time passcode (if Screen Time is active).
2. Tap Reset to confirm.

If that doesn’t help, perform an all-settings reset instead. To do that, reset the steps above but select Reset All Settings in step 3.

A network settings or an all-settings reset wipes saved Wi-Fi networks and passwords on your iPad. Manually join a Wi-Fi hotspot afterward or use cellular data.

Perform iPadOS Update via Finder or iTunes

If Over-the-Air updates repeatedly fail on your iPad, you must update the device via the Finder app on a Mac. If you use a PC, you must use iTunes; download iTunes via the Microsoft Store if you don’t already have it.

1. Connect your iPad to your macOS or Windows computer via USB.
2. Select your iPadOS device in Finder or iTunes.
3. Unlock your iPad and tap Allow or Trust (if you haven’t previously connected it to the same computer).
4. Select Back Up Now to back up your data (optional).
5. Select the Check for Updates or Update Now button.

1. Select Download and Update and Agree to the software update license terms.
2. Wait until Finder or iTunes downloads the latest version of the device software and firmware in IPSW (iPhone Software) format from the Apple servers. It will then perform the update automatically. Do not disconnect your iPad in the meantime.

Alternatively, you can download the latest version of iPadOS manually via IPSW.me. Then, hold the Option/Alt key while selecting the Check for Updates or the Update Now button (in step 5) and select the IPSW file from your computer’s Downloads folder.

Software Update Failed Error on iPad Fixed

“Software Update Failed” on the iPad is a straightforward error to fix; deleting the downloaded update file, performing a device reboot, and freeing up storage space almost always works. If not, work through the other fixes, and you should be able to get the latest version of iPadOS running on your iPad soon.
