xubuntu-14.04 系統在啓動過程當中關於無線網卡的錯誤信息（已解決）

看樣子好像是無線網卡方面的問題，暫不影響使用，無線網卡在啓動後也能正常使用。 硬件信息以下： $ lspci 07:00.0 Ethernet controller: Qualcomm Atheros QCA8171 Gigabit Ethernet (rev 10) 08:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01) 系統內核版本： $ uname -a Linux myhost 3.13.0-44-generic #73-Ubuntu SMP Tue Dec 16 00:22:43 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

先記錄在這裏，待空了再解決。 昨天晚上搞定：是無線網卡Broadcom Corporation BCM43142 的固件方面的問題，具體的緣由我還描述不出來？ 就是安裝firmware-b43-installer 　b43-fwcutter，其中後者會自動從網上下載一個包含了網卡固件的壓縮包，解壓在系統下/lib/firmware/b43/目錄下。以後，重啓系統，就不會再報錯了:-)

不過問題又來了，　我看了這２個軟件安裝包的文件信息： user@myhost:~$ dpkg -L b43-fwcutter /. /usr /usr/share /usr/share/man /usr/share/man/man1 /usr/share/man/man1/b43-fwcutter.1.gz /usr/share/doc /usr/share/doc/b43-fwcutter /usr/share/doc/b43-fwcutter/README /usr/share/doc/b43-fwcutter/copyright /usr/share/doc/b43-fwcutter/NEWS.Debian.gz /usr/share/doc/b43-fwcutter/changelog.Debian.gz /usr/bin /usr/bin/b43-fwcutter

就是系統在解壓並安裝完軟件包後，自動從網上下載驅動的腳本，是哪裏？ １、關於dpkg-deb方面還有待仔細瞭解。 ２、另外，在gentoo下也有一樣的錯誤日誌，等空了也把它解決掉。
