Detect and Fix Proxmox file integrity issue
The files can be easily corrupted if the Proxmox OS is installed on an USB device.
Because Proxmox uses Debian system, run following command to detect corruption
# dpkg --verify ??5?????? c /etc/apt/sources.list.d/pve-enterprise.list ??5?????? c /etc/lvm/lvm.conf ??5?????? c /etc/issue #
Above files can be ignored as reason below.
/etc/apt/sources.list.d/pve-enterprise.list: Not using enterprise repo
/etc/lvm/lvm.conf: LVM configuration file contains system specific info, such as UUIDs
/etc/issue: This file contains IP address of host
Find out the packages
# dpkg -S <list of file_name>
Reinstall the packages
apt --reinstall install <list of package_name>
