    <p>Ahoy there.</p> <p>So I have Debian installed on my raspberry pi, and everything has been going great, but somewhere along the line my apt-get broke. Now whenever i try to install or remove anything, it fails and returns errors messages like this one:</p> <pre><code>debconf: Perl may be unconfigured (Quantifier follows nothing in regex; marked by &lt;-- HERE in m/* &lt;-- HERE nostdio.h * * Copyright (C) 1996, 2000, 2001, 2005, by Larry Wall and others * * You may distribute under the terms of either the GNU General Public * License or the Artistic License, as specified in the README file. * */ at /usr/lib/perl/5.10/IO.pm line 8.

Where else might I look for clues, and how might I repair my apt-get installation?</p> <p>I guess this hints at a larger issue too: I consider myself a competent web programmer, with about 10 years of front end and backend experience, but linux library/compilation errors still feel like I'm reading Etruscan. Are there any good docs on diagnosing common types of compilation/installation errors in Linux so that I can feel less like I'm typing in a magic spell I found on Google, and more like I actually am understanding my solutions?</p> <p>Thank you, Internet.</p>

    1. COAll tools are more or less different in the details but most share some heritage with tools from the olden days. Typically you need to be very picky when reading an error report like this one and go to the `perl` documentation to see what `require` means. If I were to guess, you've managed to remove some (central) module in your `perl` installation which generates this error.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
