我的sources.list是 deb http://debian.ustc.edu.cn/debian testing main non-free contrib deb-src http://debian.ustc.edu.cn/debian testing main non-free contrib deb http://debian.ustc.edu.cn/debian-security testing/updates main deb http://debian.ustc.edu.cn/debian-uo sid marillat ustc rareware misc 昨天运行aptitude update 和aptitude upgrade后，再次运行aptitude update出现如下错误 # aptitude update Get:1 http://debian.ustc.edu.cn testing Release.gpg [189B] Get:2 http://debian.ustc.edu.cn testing/updates Release.gpg [189B] Get:3 http://debian.ustc.edu.cn sid Release.gpg [189B] Hit http://debian.ustc.edu.cn testing Release Hit http://debian.ustc.edu.cn testing/updates Release Hit http://debian.ustc.edu.cn sid Release Hit http://debian.ustc.edu.cn testing/main Packages/DiffIndex Hit http://debian.ustc.edu.cn testing/non-free Packages/DiffIndex Hit http://debian.ustc.edu.cn testing/contrib Packages/DiffIndex Hit http://debian.ustc.edu.cn testing/main Sources/DiffIndex Hit http://debian.ustc.edu.cn testing/non-free Sources/DiffIndex Hit http://debian.ustc.edu.cn testing/contrib Sources/DiffIndex Ign http://debian.ustc.edu.cn testing/updates/main Packages/DiffIndex Get:4 http://debian.ustc.edu.cn sid Release [14.2kB] Ign http://debian.ustc.edu.cn sid Release Hit http://debian.ustc.edu.cn testing/updates/main Packages Ign http://debian.ustc.edu.cn sid/marillat Packages/DiffIndex Ign http://debian.ustc.edu.cn sid/ustc Packages/DiffIndex Ign http://debian.ustc.edu.cn sid/rareware Packages/DiffIndex Ign http://debian.ustc.edu.cn sid/misc Packages/DiffIndex Hit http://debian.ustc.edu.cn sid/marillat Packages Hit http://debian.ustc.edu.cn sid/ustc Packages Ign http://debian.ustc.edu.cn sid/rareware Packages Hit http://debian.ustc.edu.cn sid/misc Packages Err http://debian.ustc.edu.cn sid/rareware Packages 404 Not Found Fetched 14.4kB in 1s (11.9kB/s) Reading package lists...
