我在 VPS 上运行 12.10，发现它不再受支持，因此我尝试升级。我关注了论坛上的一个帖子，并执行以下操作：
更新了 sources.list 文件：

sudo apt-get update; sudo apt-get upgrade -y这失败了，抱怨字体配置：
Setting up fontconfig (2.11.0-0ubuntu4.1) ... Regenerating fonts cache... failed. See /var/log/fontconfig.log for more information. dpkg: error processing package fontconfig (--configure): subprocess installed post-installation script returned error exit status 1 Setting up apt-utils (1.0.1ubuntu2.6) ... Errors were encountered while processing: fontconfig E: Sub-process /usr/bin/dpkg returned an error code (1)cat /var/log/fontconfig.log给我：/usr/share/fonts: caching, new cache contents: 0 fonts, 1 dirs /usr/share/fonts/truetype: caching, new cache contents: 0 fonts, 1 dirs /usr/share/fonts/truetype/ttf-dejavu: caching, new cache contents: 6 fonts, 0 dirs /usr/X11R6/lib/X11/fonts: skipping, no such directory /usr/local/share/fonts: caching, new cache contents: 0 fonts, 0 dirs /.local/share/fonts: fc-cache: symbol lookup error: fc-cache: undefined symbol: FcStrListFirst
我尝试清除并重新安装字体配置，调用fc-cache -f重建缓存，但无济于事。有什么想法吗？
谢谢，伊万

我使用 purge 删除了 fontconfig-config，之后一切都开始正常工作：
apt-get remove --purge fontconfig-config
