E: Unable to locate package Kdevelop-dev 这是一个小伙伴安装软件包时出现的问题，其实LZ通过
sudo apt-get install name 1
安装软件的时候也会经常不记得一些依赖项的具体名字，毕竟脑容量有限，只能记得关键词，下面就以Kdevelop为例。
sudo apt-cache search Kdevelop //以下为输出 c-cpp-reference - C and C++ programming reference kdev-python - KDevelop Python Plugin kdevelop - integrated development environment for KDE kdevelop-data - data files for the KDevelop IDE kdevelop-dbg - debugging symbols for KDevelop kdevelop-dev - development files for the KDevelop IDE kdevelop-l10n - localization files for the KDevelop IDE kdevelop-pg-qt - LL(1) parser generator based on Qt kdevelop-php - PHP plugin for KDevelop kdevelop-php-dbg - debugging symbols for the KDevelop PHP plugin kdevelop-php-docs - PHP documentation plugin for KDevelop kdevelop-php-docs-l10n - localization files for KDevelop PHP documentation plugin kdevelop-php-l10n - localization files for KDevelop PHP plugin kdevplatform-dbg - debugging symbols for the KDevelop platform kdevplatform-dev - development files for the KDevelop platform kdevplatform-l10n - language package for the KDevelop platform kdevplatform7-libs - shared libraries for the KDevelop platform libkomparediff2-4 - Library to compare files and strings libkomparediff2-dev - Library to compare files and strings - development files libsublime-dev - development files for the sublime user interface library libsublime7 - User interface library qdevelop - A development environment entirely dedicated to Qt4 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25
可以对照自己的需求进行安装了?(^?^*)按照上面输出显示：
sudo apt-get install Kdevelop 1
可能是ubuntu内核更新，包名也会经常改变，如果遇到这种sudo apt-get update后发现还是没有找到对应的包名，那就使用sudo apt-cache search keyword
