Thank Tim, i use debian-11.6.0-amd64-netinst.iso, i don't use
unofficial images
after recognition it shall prompt me for non-free firmware, but it
can't recognize it
One approach you might be able to use is to copy the firmware that
buster is using and place it in the equivalent location in your
bullseye.
For example, my NIC uses (as seen by dmesg):
r8169 0000:03:00.0: firmware: direct-loading firmware rtl_nic/rtl8168g-2.fw
and my old buster installation on this machine has that file at:
$ ls -l /buster/lib/firmware/rtl_nic/rtl8168g-2.fw
-rw-r--r-- 1 root root 4896 Aug 22 2019 /buster/lib/firmware/rtl_nic/rtl8168g-2.fw
$
(/buster is where I mounted the old buster root filesystem,
readonly, when bullseye is running.)
My bullseye has:
$ ls -l /lib/firmware/rtl_nic/rtl8168g-2.fw
-rw-r--r-- 1 root root 4896 Jul 25 2021 /lib/firmware/rtl_nic/rtl8168g-2.fw
$
and cmp shows that the two versions are identical, despite the timestamps.
Just take care to create any subdirectories required (like the rtl_nic
here).
Cheers,
David.
