/dev/null permission denied in chroot environment

I have Xubuntu 18.04 in a chroot environment. I just dropped it in there from a VM I had of it.

Going into the chroot environment, if I try to run apt update I get this error:

/usr/bin/apt-key: 624: /usr/bin/apt-key: cannot create /dev/null: Permission denied

I have tried most of the solutions here: https://unix.stackexchange.com/questions/146633/bash-dev-null-permission-denied As well as this solution: https://superuser.com/a/814594 Neither worked. Same exact output.

Is there some way I can get this working? Thanks in advance.

Solution 1:

From man null:

   These devices are typically created by:

          mknod -m 666 /dev/null c 1 3
          mknod -m 666 /dev/zero c 1 5
          chown root:root /dev/null /dev/zero

These commands would have to be executed in the chroot environment.

Solution 2:

Figured out the issue. It wasn't readable/writable by all users. Changed it so all users could read and write and it worked. Thanks anyways!
