我是 Ubuntu 的新手，正在使用安裝了 Ubuntu 16.04 的 UP BOARD。
我按照這個安裝iwlwifi：https://github.com/HappyZ/iw_intel8260_localization/wiki/Enable-802.11mc-FTM-on-Intel-8260
安裝時，在“ sudo make -j4 ”之後，我得到了許多“ symbolmap：00000001：無效部分”。
像這樣 ：
symbolmap: 00000001: invalid section
CC [M] /lib/firmware/backport-iwlwifi/net/mac80211/aes_gcm.o
symbolmap: 00000001: invalid section

CC [M] /lib/firmware/backport-iwlwifi/net/mac80211/aes_gmac.o
symbolmap: 00000001: invalid section
我不知道這是錯誤還是正常。
在“ sudo make install ”之後，我得到了
$ sudo make install
INSTALL /lib/firmware/backport-iwlwifi/compat/compat.ko
At main.c:160:
- SSL error:02001002:system library:fopen:No such file or directory: bss_file.c:175
- SSL error:2006D080:BIO routines:BIO_new_file:no such file: bss_file.c:178
sign-file: certs/signing_key.pem: No such file or directory
不過按照導遊的說法，沒問題。
當我重新啟動時，我得到了
$ cat /var/log/syslog | grep -a iwlwifi

當我完成本教程的其餘部分時，一切都顯示正確，只是最終結果與預期不同。
表明
Target: 38:de:ad:27:d0:e9, status: 4, rtt: 0 psec, distance: 0 cm
但不是
status: 0
這意味著我失敗了。根據作者的說法，我重新執行了這些步驟，但仍然失敗。
請問，我能做什麼？
我查找了相關主題並嘗試了一些解決方案。
根據無法偵測無線驅動程式 intel ac wireless 9560 [包含日誌]，我做了：
sudo apt update
sudo apt upgrade
重新啟動後，我得到了這個：
$ dmesg | grep iwl

看來是不行了。
另外，升級後，我的韌體檔案包括：
iwlwifi-8000C-34.ucode
iwlwifi-8000C-36.ucode
