那您解决了吗？我给ubuntu留言他们说不用那个文件就可以，他们说那个文件被打包进了said. bin. 这里实效性太差，如果方便可以交流。chance2006…163.com

升级中看到了你的回复，忐忑的重启了，果不其然，无线网卡找不到了。。。

对了ubuntu官方给出的办法中
https://wiki.ubuntu.com/ARM/RaspberryPi
WiFi

Since 18.04.2 the linux-firmware and linux-firmware-raspi2 packages now contain the necessary files for the built-in WiFi on the Pi 3B, 3B+, and 4B. However, if for some reason you want the latest and greatest files:

mkdir wifi-firmware
cd wifi-firmware
# Pi 3B
wget https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm/brcmfmac43430-sdio.bin
wget https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm/brcmfmac43430-sdio.clm_blob
wget https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm/brcmfmac43430-sdio.txt
# Pi 3B+ and 4
wget https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm/brcmfmac43455-sdio.bin
wget https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm/brcmfmac43455-sdio.clm_blob
wget https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm/brcmfmac43455-sdio.txt
sudo cp *sdio* /lib/firmware/brcm/
cd ..
Reboot the machine.

Use dpkg-divert to stop these files being overwritten on package updates.
有一个文件是404 not found我打开了ubuntu在github中的仓库确实缺失一个文件.clm_blob的文件
不过依然还是要，感谢楼主的办法分享让我能往前走，用有线也是可以的

今天才搞清楚这个错误的原文的意思是树莓派的自带蓝牙相关升级和wifi有冲突，其中后面提到了无线网卡的型号brcmfmac43430和43435注意树莓派3b可能是这两款中的任意一款,所以按照楼主的做法搞完后不能无线上网。等我找到更合适的做法，我再分享

不确定，我没有测试过。或许过了这么长时间，官方已经解决这个问题了？
