Although I have found many other posts on this exact problem, none of their presented solutions have fixed my issue.
I have configured and SFTP and SSH server on my raspberry pi. And ever since I enabled the SFTP server, non-admin accounts cannot ssh into the raspberry pi anymore, being presented with this message:
Last login: Sat Jul 15 12:02:42 2023 from 192.168.1.221
/bin/bash: No such file or directory
Connection to xxx.yyy.z.vvv closed.
I have followed the advice online and created in my chroot directory (see sshd_config file below) a bin folder with the copied bash file inside it. However, nothing changed. I tried also adding the same folder into the home directory of the user I was trying to log in from, but once again - No change.
My knowledge of linux is way to limited to know where to go from there. I'll be happy to recieve any advice as to what to troubleshoot next.
Thank You for your help.
As mentioned above, the complete sshd_config file: (My own configuration starts after the Subsystem line, I have not messed with anything above it)
# $OpenBSD: sshd_config,v 1.103 2018/04/09 20:41:22 tj Exp $
# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.
# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin
# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options override the
# default value.
