如何更改已安装磁盘上目录的所有权？

磁盘分区/dev/sda7已安装/media/debian/8eda3aeb-e21b-455f-bb7a-f46005fb4893，我想更改目录的所有权/media/debian/8eda3aeb-e21b-455f-bb7a-f46005fb4893/mydoc，

sudo chown -R  debian:debian /media/debian/8eda3aeb-e21b-455f-bb7a-f46005fb4893/mydoc

它遇到如下问题：

chown: changing ownership of '/media/debian/8eda3aeb-e21b-455f-bb7a-f46005fb4893/mydoc': Operation not permitted

如何修复它？
显示 uuid 和文件类型：

sudo blkid |grep sda7
/dev/sda7: UUID="B8DC-0104" TYPE="vfat" PARTLABEL="win10" PARTUUID="cdbdb58a-158d-428b-b572-5d4a2ad391c9"

以此方式安装，

cat /etc/fstab
UUID=B8DC-0104    /media/debian/8eda3aeb-e21b-455f-bb7a-f46005fb4893  vfat  rw,user,exec,umask=000 0 0

尝试像@waltinator所说的那样 安装脂肪

步骤1：删除/etc/fstab上的设置，删除以下行

UUID=B8DC-0104    /media/debian/8eda3aeb-e21b-455f-bb7a-f46005fb4893  vfat  rw,user,exec,umask=000 0 0

步骤2：重新启动步骤3：

target=/dev/sda7
mntdir=/mnt/wordpress
sudo mkdir mntdir
sudo mount -t vfat -o remount,rw,user,users,nosuid,nodev,relatime,uid=$(id -u),gid=$(id -g),fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2 $target $mntdir

错误信息：

mount: /mnt/wordpress not mounted or bad option

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

答案1

由于sudo不起作用，请运行su，输入 root 密码，然后运行chown -R debian:debian /media/debian/8eda3aeb-e21b-455f-bb7a-f46005fb4893/mydoc​​。应该工作。
