Updates to Linux on Pogoplug v4

Posted on by

I have an old Pogoplug v4 series hacked to install Debian Linux based on this instruction long ago: http://blog.qnology.com/2014/07/hacking-pogoplug-v4-series-4-and-mobile.html
which boots on an SD card, which I used as a no-ip update client.

I realized some of the URLs to the package servers are broken. So here’s my notes to update it.

First apt-get doesn’t work anymore because the files has been moved to the archive package server. The solution is to replace all the contents (now obsolete) in /etc/apt/sources.list by this line:

deb http://archive.debian.org/debian wheezy main

Then you update the package manager (apt-get) with this command:

apt-get update && apt-get upgrade

Note that it’s still Debian 7 and it will not work with new software that requires later versions

NextCloud quirks – moving folder breaks the site

I changed the folder of where my NextCloud files is and got this error.

Adding the “.ocdata” dummy file there doesn’t work. The message is cryptic. I tried to run occ at the root folder (hoping it’s some sort of management tool) by running this at the command/SSH prompt:

php ./occ

and it spits out:

Your data directory is invalid
Ensure there is a file called ".ocdata" in the root of the data directory.

An unhandled exception has been thrown:
Exception: Environment not properly prepared. in 
{New Folder}/lib/private/Console/Application.php:168
Stack trace:
#0 {New Folder}/console.php(99): ...

I replaced my actual path for the new location of the NextCloud files with {New Folder}, so you get the idea.

I also noticed the old path was regenerated with just a /data folder with two files

This means some programmer got lazy and hard-coded the path somewhere!

Line 99 of console.php didn’t give too much hint so I looked at the code around for some sort of config-related operations before. Then I noticed this:

So I searched for config.php and found it’s located in /config/config.php. Bingo!

<?php
$CONFIG = array (
...
  'trusted_domains' => 
  array (
    0 => '{Old URL}',
  ),
  'datadirectory' => '{Old Path}/data',
...
  'overwrite.cli.url' => 'https://{Old URL}',
...
);

And to my horror the SQL password is stored in plain text in config.php! WTF! I’ll choose a password that’s dedicated to one use and not shared!

I recalled a when I rename WordPress databases, I have to manually edit the changes in wp-config.php. Turns out nobody warned us about that for NextCloud! That config file also contain database settings, so I bet if I change the database names or database usernames, I’ll have to come back and edit it manually too.

The site is working after I made the migration changes, all in /config/config.php.
