有报错error while loading shared libraries: libXp.so.6

所以在网上搜索如何安装去这个网站看了
http://www.linuxdiyf.com/viewarticle.php?id=108903

现在是已经有了这个文件，但系统就是找不到，如图所示

谁能告诉我怎么用 apt-get install 来装啊，

就是install后面加什么有这个库呢

sudo apt install libxp6

显示无法定位软件包

sudo apt update了没

这个还没有，我正在运行，好长时间了

获取：143 http://security.ubuntu.com wily-security/main Translation-en [279 kB]
这个有好多

都4000多了，这是个啥，update还没完

怎么会那么多。。。。
/etc/apt/sources.list文件内容复制上来看看

是不是要注释掉哪个

我注释了那个网站，跳过了那几千个

现在变成这样了

sources文件没什么问题，那就安装libxp6吧

兄弟，依然无法定位软件包

额，貌似是个bug？ https://bugs.launchpad.net/ubuntu/+sour ... ug/1517884

http://mirrors.ustc.edu.cn/ubuntu/pool/main/libx/libxp/ 去这里下载deb安装试试

也可以试试sudo apt install libxp-dev

跪谢，deb就ok了，

再顺便问一下，如果报错缺少哪个库，我咋知道apt get install 后面加什么呢

有没有搜索软件包的指令，还有就是我按一开始那个教程，算是源码安装吗，安装好电脑里有libxp6的库了已经（如一楼所示），但系统仍提示找不到，怎么给系统添加路径呢

apt-file 可以查找 viewtopic.php?f=120&t=188146
那个教程不是源码安装，系统安装的库文件要放在合适的目录下才行，可能是你放的位置不对也可能是别的问题，不太了解
添加路径是说系统库文件路径？不了解
