SSH for my_webapp and installing chroot os with the help of debootstrap

Hi guys, I opened a new thread because even by following these steps, stuff breaks… Do you have any idea about what is wrong?

Note

While performing debootstrap install, I get the following error:

W: Failure trying to run: chroot "/var/www/my_webapp" dpkg --force-overwrite --force-confold --skip-same-version --install /var/cache/apt/archives/libapparmor1_2.13.6-10_amd64.deb /var/cache/apt/archives/libargon2-1_0~20171227-0.2_amd64.deb /var/cache/apt/archives/libcryptsetup12_2%3a2.3.7-1+deb11u1_amd64.deb /var/cache/apt/archives/libip4tc2_1.8.7-1_amd64.deb /var/cache/apt/archives/libjson-c5_0.15-2_amd64.deb /var/cache/apt/archives/libkmod2_28-1_amd64.deb /var/cache/apt/archives/libcap2_1%3a2.44-1_amd64.deb /var/cache/apt/archives/dmsetup_2%3a1.02.175-2.1_amd64.deb /var/cache/apt/archives/libdevmapper1.02.1_2%3a1.02.175-2.1_amd64.deb /var/cache/apt/archives/systemd_247.3-7+deb11u1_amd64.deb
