Google Chrome 无法启动 - 无法在 module_path 中找到主题引擎：“adwaita”

Question

谷歌浏览器在最近的apt-get upgrade. 我不知道我错过了什么，而且谷歌没有为这些错误找到很多结果：

$ google-chrome --version
Google Chrome 42.0.2311.152

升级前 Chrome 在这台机器上运行良好。

该问题似乎仅发生在 64 位 Ubuntu 系统上的 i386 版本的 Google Chrome 上。这是 32 位与 64 位问题的提示是，安装:i386某些软件包的版本会使一些错误消失。通过安装 64 位版本，我能够让 Chrome 再次运行：

$ sudo aptitude install google-chrome-stable

The following packages have unmet dependencies:
 libappindicator1 : Conflicts: libappindicator1:i386 but 12.10.1+15.04.20141110-0ubuntu1 is installed.
 libappindicator1:i386 : Conflicts: libappindicator1 but 12.10.1+15.04.20141110-0ubuntu1 is to be installed.
 google-chrome-stable : Conflicts: google-chrome-stable:i386 but 42.0.2311.152-1 is installed.
 google-chrome-stable:i386 : Conflicts: google-chrome-stable but 42.0.2311.152-1 is to be installed.
 libindicator7 : Conflicts: libindicator7:i386 but 12.10.2+14.10.20140922-0ubuntu1 is installed.
 libindicator7:i386 : Conflicts: libindicator7 but 12.10.2+14.10.20140922-0ubuntu1 is to be installed.
The following actions will resolve these dependencies:

     Remove the following packages:
1)     google-chrome-stable:i386   
2)     libappindicator1:i386       
3)     libindicator7:i386          

Accept this solution? [Y/n/q/?] 

我接受了建议的解决方案，将多个软件包升级到 64 位版本，Chrome 又可以正常工作了。
