解決方案

清空緩存
```
pkg update -f
```

刪除pkg緩存和數據庫

pkg clean # cleans /var/cache/pkg/
rm -rf /var/cache/pkg/* # just remove it all
pkg update -f # forces update of repository catalog
rm /var/db/pkg/repo-*.sqlite # removes all remote repository catalogs
pkg bootstrap -f # forces reinstall of pkg

更換pkg源

把pkg的源從南京大學的更換到中國科學技術大學的就解決了.(實際上上面的步驟我执行了之后并没有解决问题，问题的原因就是南大的源可能有问题。)
```
change http://mirrors.nju.edu.cn/freebsd-pkg/${ABI}/quarterly --> http://mirrors.ustc.edu.cn/freebsd-pkg/${ABI}/quarterly
```
