fatal: cannot make /home/xxxx/work/dove13/.repo/repo directory: File ex

kkkkcom@kkkkcom-virtual-machine:/snap/bin$ ls -l repo
lrwxrwxrwx 1 root root 13 5月 16 09:38 repo -> git-repo.repo
kkkkcom@kkkkcom-virtual-machine:/snap/bin$ ls -l git-repo.repo
lrwxrwxrwx 1 root root 13 5月 16 09:38 git-repo.repo -> /usr/bin/snap

这里直接去修改用户组发现并不能生效，可能跟链接L文件有关，于是通过rm -rf把有问题的repo删除，并且将实体机里面的repo文件拷贝到相关路径并设置相同的权限和用户组，发现问题解决

rm -rf /snap/bin/repo

kkkkcom@kkkkcom:kkkkcom-virtual-machine:/snap/bin$ sudo cp ~/Desktop/repo .
kkkkcom@kkkkcom-virtual-machine:/snap/bin$ ls -l repo
-rw-r–r-- 1 root root 45277 5月 26 10:40 repo
kkkkcom@kkkkcom-virtual-machine:/snap/bin$ sudo chown kkkkcom:kkkkcom repo
kkkkcom@kkkkcom-virtual-machine:/snap/bin$ ls -l repo
-rw-r–r-- 1 kkkkcom kkkkcom 45277 5月 26 10:40 repo
kkkkcom@kkkkcom-virtual-machine:/snap/bin$ chmod 775 repo
kkkkcom@kkkkcom-virtual-machine:/snap/bin$ ls -l repo
