$ sudo apt-get install git
$ git clone sth
克隆到“a-folder”... git-remote-https：符号查找错误：/usr/lib/x86_64-linux-gnu/libhogweed.so.2：未定义符号：__gmpn_cnd_add_n
这个帖子告诉我删除/usr/local/lib/libgmp.so.10。我这样做了，它有效，但时不时地提示相同的错误（自从重新启动以来？）
我认为删除文件并不能真正解决问题。有更可靠的解决方案吗？

您需要完全删除本地libgmp：
rm /usr/local/lib/libgmp.so*
以后就没必要跑了ldconfig。ldconfig确保存在适当的符号链接；libgmp.so.10是具有该soname的最新库的符号链接（ls -l /usr/local/lib/libgmp.so*在删除文件之前运行以了解我的意思）。之前您删除了该符号链接，但运行ldconfig将恢复它......
