Chromium 浏览器一直运行良好，直到今天。我尝试运行它并收到以下错误消息：
/usr/lib/chromium-browser/chromium-browser: /usr/local/lib/libz.so.1: no version information available (required by /usr/lib/x86_64-linux-gnu/libcups.so.2)
/usr/lib/chromium-browser/chromium-browser: /usr/local/lib/libz.so.1: no version information available (required by /usr/lib/x86_64-linux-gnu/libgio-2.0.so.0)
/usr/lib/chromium-browser/chromium-browser: relocation error: /usr/lib/x86_64-linux-gnu/libcups.so.2: symbol inflateCopy, version ZLIB_1.2.0 not defined in file libz.so.1 with link time reference
我甚至删除了它（apt-get remove --purge chromium-browser）并重新安装它，但仍然出现相同的错误。这是什么意思？我该怎么办？
编辑：这是在 Ubuntu 14.04 上
