環境：kali linux
我在用
apt autoremove git
卸載git的時候，想在安裝，結果顯示無法解析域名，害我搞了半天
ping www.baidu.com
域名不解析成ip，則是dns配置問題。
然後修改resolv.conf配置
vim /etc/resolv.conf
nameserver 202.96.134.133
nameserver 114.114.114.114
nameserver 8.8.8.8
然後把原來的替換掉，然後記得重啓啊，應該就可以了。
有一次我用apt-get update更新的時候，域名又不解析了
環境：小米6的nethunter，任何手機都可刷kali.

域名解析
那應該不是dns配置問題
更換更新源,但還是沒解決
，找了半天，終於找到了答案,在github找到了答案。
修改/etc/passwd
vim /etc/passwd
修改
_apt: x: 104: 3004 :: / nonexistent: / bin / false
爲
_apt: x: 0: 65534 :: / nonexistent: / bin / false
就是把“104"改成"0"
這樣改成功域名解析。
