Need to get 61.3 MB of archives.
After this operation, 146 MB of additional disk space will be used.
apt-get autoremove没有输出，这意味着The following packages were automatically installed and are no longer required是因为 Skype。
为什么包skype过时了这么多（可能很重要！）与 Java 相关的包，我可以同时拥有这两个包吗？这是 Ubuntu 15.10。
apt-get purge skype给Package 'skype' is not installed, so not removed.
安装其他软件包可以提供，例如，
The following extra packages will be installed:
libfinance-yahooquote-perl
The following NEW packages will be installed:
libfinance-yahooquote-perl smtm
0 upgraded, 2 newly installed, 0 to remove and 0 not upgraded.
所以它是特定于 Skype 的。
评论中建议我一一删除“以下软件包将被删除”中的每一个，以查看哪些给出了长长的删除列表，我这样做了：
A=$(for i in `echo automoc firebird-dev firebird2.5-server-common kdelibs5-dev libfbembed2.5 libkrb5-dev libmysqlclient-dev libphonon-dev libpq-dev libqt4-dev libqt4-opengl-dev libqtwebkit-dev libreoffice-subsequentcheckbase libsqlite0-dev python-sqlite-dbg qt4-designer qt4-dev-tools unixodbc-dev`
do echo; echo PACKAGE IS $i IS PACKAGE
echo; echo -e '\04' | apt remove $i; done
)
printf "$A" > a
我最终得到了以下列表：
automoc
kdelibs5-dev
libmysqlclient-dev
libphonon-dev
libpq-dev
libqt4-dev
libreoffice-subsequentcheckbase
unixodbc-dev
所以现在的问题更像是，为什么这些软件包需要被 Skype 删除，为什么它们会导致一长串的废弃？
我最终继续删除一长串软件包，然后重新安装它们，效果很好。
