我在 Ubuntu 下使用 LaTeX+Biber+Texmaker。我最近将 Ubuntu 从 12.10 升级到 14.10，之后我的一些 LaTeX 文档出现了一些问题。我认为问题可能是由于缺少 LaTeX 软件包造成的，因此我还安装了 texlive-full (http://packages.ubuntu.com/utopic/texlive-full)，它将收集 Ubuntu 存储库中的所有 tex 包。错误日志返回一组错误，如下所示：

我发现最相似的问题是Biblatex 与 biber 后端一起使用会导致未定义的控制序列，但与 bibtex 后端一起使用则不会如此，但我不确定这是否与同一个问题有关。
对于可能存在什么问题您有什么想法吗？
非常感谢！

按照@Joseph Wright 的建议，删除辅助文件后解决了这个问题。升级版本后似乎有必要这样做。
