Notes on Migrating UniFi-Video NVR Disk

Recently upgraded a UniFi-Video VM by creating a new VM and restoring the backup from the previous one. There was a separate virtual disk used for storing all the videos. Although once I reattached it, I had to change the owner to the unifi-video user. lt was reporting that the owner/group was 127 and 134, looks like that was the user ID from the previous VM.

Example output from ls -hla command

drwxr-xr-x 3 127 134 4.0K Jan 16 2020 176de761-8399-3bed-8ceb-917cbe4d25bd
drwxr-xr-x 2 127 134 4.0K Sep 10 12:28 21d506ef-dded-31f2-baf8-c109a7e653b9
drwxr-xr-x 4 127 134 4.0K Jan 1 2020 1a3afc4c-a030-39a1-b139-857444c8b71c

Ended up changing the owner to the unifi-video owner with the chown command. /path/to/videos is the mount point of the video drive.

chown -R unifi-video:unifi-video /path/to/videos

Change UniFi Camera Password from Command Line

Basic steps are

  • Change password with passwd
  • Copy passwd hash to /tmp/system.cfg
  • Apply Changes

Changing Password with passwd

The passwd command is normally used for changing the password for a Linux user. We’ll use it to change our user password and then copy the hash out of the /etc/passwd file to use in the Ubiquiti config file.

UVC.v4.18.37.67# passwd
Changing password for admin
New password:
Retype password:
passwd: password for admin changed by admin
UVC.v4.18.37.67#

Copy passwd hash to /tmp/system.cfg

Using “cat /etc/passwd”, we can get what the new password hash is and can copy that into the /tmp/system.cfg file.

UVC.v4.18.37.67# cat /etc/passwd
admin:$6$K4VfN1jGcxaX63Eo$yMGBg7jgCCg.HorkmkQf9wnQcEko.1onZcAa6ua421LonYgfYr8FgHprrwkMqaTYzH0KqCtOEPqDlB3AvkvcW.:0:0:Administrator:/etc/persistent:/bin/sh
UVC.v4.18.37.67#

Open up the /tmp/system.cfg config file, find the section below and replace the hash part, i.e. the part that is in bold.

users.1.name=admin
users.1.password=$6$K4VfN1jGcxaX63Eo$yMGBg7jgCCg.HorkmkQf9wnQcEko.1onZcAa6ua421LonYgfYr8FgHprrwkMqaTYzH0KqCtOEPqDlB3AvkvcW.
users.1.status=1

As a side note, you can copy and past all of the “users.1.*” lines and change the 1 to 2 and have a second user.

Apply Changes

You can use the following command to write the changes and then reboot the camera.

cfgmtd -f /tmp/system.cfg -w && reboot

Long Example

[admin@localhost ~]$ ssh ubnt@10.96.1.91
ubnt@10.96.1.91's password:
BusyBox v1.29.2 () built-in shell (ash)
UVC.v4.18.37.67# passwd
Changing password for admin
New password:
Retype password:
passwd: password for admin changed by admin
UVC.v4.18.37.67# cat /etc/passwd
admin:$6$K4VfN1jGcxaX63Eo$yMGBg7jgCCg.HorkmkQf9wnQcEko.1onZcAa6ua421LonYgfYr8FgHprrwkMqaTYzH0KqCtOEPqDlB3AvkvcW.:0:0:Administrator:/etc/persistent:/bin/sh
UVC.v4.18.37.67# vi /tmp/system.cfg <- Edit the text file and replace the hash with the one from above
UVC.v4.18.37.67# cfgmtd -f /tmp/system.cfg -w && reboot

MongoDB – dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)

Ran into an issue when trying to figure out some problems with UniFi and UniFi-Video. Upgrading both to the latest version was causing problems, because they both needed different versions of MongoDB.

Was getting the following error when trying to install MongoDB. Think I was trying to install Mongo following the instructions on their site and then it caused issues with apt.

dpkg: error processing archive /var/cache/apt/archives/mongodb-org-server_4.2.5_amd64.deb (--unpack):
trying to overwrite '/usr/bin/mongod', which is also in package mongodb-server-core 1:3.6.3-0ubuntu1.1
dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)

Removed the following file

rm /etc/apt/sources.list.d/mongodb-org-4.2.list

and was able to use apt again to install MongoDB. Didn’t end up solving my problem because I technically needed two versions, but at least apt was being nice again. Ended up installing the UniFi controller docker container and can run both on the same server that way.
