Docker busybox tar сломанный канал

Вы должны извлечь файл .deb, затем скопировать его на свой USB-накопитель, когда вас попросят загрузить недостающую прошивку, подключите USB, есть пример:

mkdir bcm && cd bcm
wget  http://ftp.us.debian.org/debian/pool/non-free/f/firmware-nonfree/firmware-brcm80211_20161130-3_all.deb
ar x firmware-brcm80211_20161130-3_all.deb
tar xvf data.tar.xz
cd /lib/firmware/brcm
ls

образец вывода:

bcm43xx-0.fw              brcmfmac4330-sdio.bin    brcmfmac4354-sdio.bin
bcm43xx_hdr-0.fw          brcmfmac43340-sdio.bin   brcmfmac43569.bin
brcmfmac43143.bin         brcmfmac4334-sdio.bin    brcmfmac4356-pcie.bin
brcmfmac43143-sdio.bin    brcmfmac4335-sdio.bin    brcmfmac43570-pcie.bin
brcmfmac43236b.bin        brcmfmac43362-sdio.bin   brcmfmac43602-pcie.ap.bin
brcmfmac43241b0-sdio.bin  brcmfmac4339-sdio.bin    brcmfmac43602-pcie.bin
brcmfmac43241b4-sdio.bin  brcmfmac43430-sdio.bin   brcmfmac4366b-pcie.bin
brcmfmac43241b5-sdio.bin  brcmfmac43455-sdio.bin   brcmfmac4371-pcie.bin

Скопируйте bcm43xx-0.fwна USB-накопитель. повторите те же шаги дляrtl_nic/rtl8168d-2.fw

Пакет прошивки=firmware-realtek

If the firmware was loaded from a firmware package, debian-installer will also install this package for the installed system and will automatically add the non-free section of the package archive in APT's sources.list. This has the advantage that the firmware should be updated automatically if a new version becomes available.

свободные файлы прошивки =rtl_nic/rtl8168d-2.fw

If the firmware was loaded from loose firmware files, the firmware copied to the installed system will not be automatically updated unless the corresponding firmware package (if available) is installed after the installation is completed.
