Ubuntu 突然断了音频，apt-get 和 flash

Question

我一直在正常使用我的电脑，直到我发现有些不对劲，然后我重新启动了它。然后我无法使用带 chrome 的 flash 浏览网页，无法从 youtube 加载 HTML5 视频。当我尝试打开 VLC 时，它说：

martin@martin-HP:~$ vlc
VLC media player 2.2.2 Weatherwax (revision 2.2.2-0-g6259d80)
[00000000016dd028] pulse audio output error: PulseAudio server connection failure: Connection refused

和声音不起作用。

当我尝试更新 apt-get 时：

** (appstreamcli:2530): WARNING **: No origin found for file fr.archive.ubuntu.com_ubuntu_dists_xenial-updates_universe_dep11_Components-amd64.yml.gz
Segmentation fault (core dumped)

看起来像是硬件问题，但 Windows 安装工作正常。我怀疑它与文件系统有关，但我不知道如何验证它。

最好的事物！

我知道这有点旧，但我在 Ubuntu GNOME 16.04.1 LTS 上使用 apt-get 遇到了同样的错误。我找到了一个旧的论坛帖子，似乎为我解决了恰当的问题。以下是它推荐的步骤：

sudo -i
apt-get clean
cd /var/lib/apt
mv lists lists.old
mkdir -p lists/partial
apt-get clean
apt-get update
cd
exit
