linux应用程序固件升级,试试用 Linux 中的 fwupd 更新 ThinkPad 固件
之前曾经介绍过 KDE 的新软件中心应用 Discover 整合了 fwupd 这个 Linux 中的固件更新功能。但是那时候用起来还是不太顺手。今天再次通过命令行尝试使用 fwupd 来更新 ThinkPad T470s 的固件，已经没有任何问题了，感觉非常方便，而且还可以选择以后再重新启动系统。
通过命令行的使用方法很简单。查询更新，
sudo fwupdmgr get-updates
如果有更新的话就可以直接下载安装，
sudo fwupdmgr update
看看我刚在 ThinkPad T470s 上查询和升级的结果(为了省地方，那些细节被我省略掉了)，
# fwupdmgr get-updates

An update requires a reboot to complete. Restart now? [y|N]: N
嗯，我很久没有更新了，所以看着内容有点多。
可以看到最后提示说需要重启系统。但是我们可以选择不立即重启。这比在 Windows 中更新固件要更便利。在 Windows 下使用 Lenovo 的升级程序更新固件的时候是需要立即重启才更新的。
不过这里的更新似乎没有 Lenovo 官网的更新及时。我看到官网提示说 BIOS 更新到 1.37 了，
1.37 (N1WUJ30W) 1.37 (N1WET58W) 1.21 (N1WHT39W) 01 2020/03/24
1.36 (N1WUJ29W) 1.36 (N1WET57W) 1.21 (N1WHT39W) 01 2019/12/23
但是这里才 0.1.36。好像版本号也不完全相同。
但是有个意外的惊喜。之前使用 Lenovo 官方的 NVME SSD 固件更新的时候，总是提示说我的 PM961 没有新固件，但是这里居然更新了。

下面的问题，BIOS 固件实际上并没有被更新，是因为 Tumbleweed 中缺少 fwupdate-efi 组件。虽然该问题已经提出来超过两年了，不过似乎没有任何进展。
更新 2020-04-04
经过重启系统以及反复尝试之后发现，BIOS 固件，也就是上面列表中的 System Firmware 和 UEFI Device Firmware，虽然总是显示更新成功，但是实际上并没有安装更新。目前原因和解决方案未知。通过 Windows 10 安装更新则没有问题。©
