在对一堆pulseaudio包进行更新后,我的麦克风停止工作.这很好,毕竟Karmic还在Alpha.我已经向启动板报告了这个错误.
同时我想恢复pulseaudio包的更新.不幸的是,没有一个软件包允许我在Synaptic上选择“强制版本”选项.我想删除它们然后安装旧的软件包,但是删除脉冲意味着删除名为ubuntu-desktop的软件包,我担心它可能会更糟糕.我很难找到旧版本的软件包,但我最终将每个* .deb下载到我的机器上.
这些是根据Synaptic的历史更新.
libpulse-browse0 (1:0.9.15-4ubuntu3) to 1:0.9.16~test4-0ubuntu1 libpulse-mainloop-glib0 (1:0.9.15-4ubuntu3) to 1:0.9.16~test4-0ubuntu1 libpulse0 (1:0.9.15-4ubuntu3) to 1:0.9.16~test4-0ubuntu1 pulseaudio (1:0.9.15-4ubuntu3) to 1:0.9.16~test4-0ubuntu1 pulseaudio-esound-compat (1:0.9.15-4ubuntu3) to 1:0.9.16~test4-0ubuntu1 pulseaudio-module-bluetooth (1:0.9.15-4ubuntu3) to 1:0.9.16~test4-0ubuntu1 pulseaudio-module-gconf (1:0.9.15-4ubuntu3) to 1:0.9.16~test4-0ubuntu1 pulseaudio-module-x11 (1:0.9.15-4ubuntu3) to 1:0.9.16~test4-0ubuntu1 pulseaudio-module-zeroconf (1:0.9.15-4ubuntu3) to 1:0.9.16~test4-0ubuntu1 pulseaudio-utils (1:0.9.15-4ubuntu3) to 1:0.9.16~test4-0ubuntu1 pulseaudio-module-udev (1:0.9.16~test4-0ubuntu1)
建议？
如果你不害怕弄脏手,最好的方法是：
apt-cache show packagename
它将根据您的sources.list定义向您显示可以安装的所有不同版本的软件包.你会得到类似的东西(这就是它的样子)：

只需查看可用的不同版本,然后执行以下操作：
apt-get install packagname=version
再次作为上面输出的示例：
apt-get install ibpulse-browse0=1:0.9.14-0ubuntu20
你可以看到我的pulseaudio来自启动板上的ppa,所以如果我想降级/恢复到由jaunty提供的原始版本,我将使用我安装的所有pulseaudio包进行上述操作.
