错误：/bin/sh：第 21 行：：没有这样的文件或目录

Question

当我将命令运行sudo bash ~/ol_code_hosting/fedora.sh ~/ol_code_hosting/all_packages.txt到以下 bash shell 脚本时（我已通过 docker 终端中的此脚本运行 bash 命令）：

#!/bin/bash
sudo service docker restart
docker rm -f container_fedora
docker image rm -f fedora:latest
sudo docker pull fedora
sudo docker run -itd --name container_fedora fedora:latest
sudo docker exec container_fedora /bin/sh -c '

#dnf install dnf
#dnf clean all
#dnf check-update
#dnf upgrade
echo "outside1"
tmpfile=$(mktemp)
echo "outside2"

while IFS= read -r package; do
    echo "inside loop"
    if dnf info "$package" >"$tmpfile"
    then
        echo "Processing $package"
        cat "$tmpfile" >>fedora_log.txt
    else
        printf "No package info for $package"
        printf "%s\n" "$package" >>packages_not_in_fedora.txt
    fi
done <"$1"

rm -f "$tmpfile"
exit'

sudo docker cp container_fedora:/fedora_log.txt ./fedora_log.txt

收到的输出：

我不知道每次都会显示这样的错误消息。有人可以帮忙吗。非常感谢！
