Lucid to Precise Kubuntu upgrade: adobe-flashplugin cannot be removed

Submitted by Druss on Mon, 2012-03-26 22:53

So I tried updating one of my boxen running the Lucid Kubuntu LTS to the new Precise Pangolin beta. During the upgrade, I received an error message stating that adobe-flashplugin could not be upgraded. I ignored it and continued with the upgrade and all went swimmingly. Once the upgrade was completed and I had rebooted, when I tried to run an apt-get update, I ran into an error with respect to the adobe-flashplugin package. When I tried to remove it, it did not work. As a stop-gap measure, I removed a number of packages that depended on it including Firefox and sun-java6.

KDE network manager disabled

Submitted by Druss on Sat, 2011-12-31 15:45

One of my laptops which is running on Kubuntu Lucid decided to stop connecting to my network today. I found that the KDE network-manager applet (or is it a plasmoid? :S) had decided to disable itself. Clicking it stated so with no option to re-enable it (nice UI, boys). Getting to the commandline and starting the network-manager service did not help. I also found that accessing the System settings networking configuration gave me corrupt XML file errors.

E: Dynamic MMap ran out of room. Please increase the size of APT::Cache-Limit

I ran into the following error when I added a new repository to my kubuntu box and ran apt-get update:
E: Dynamic MMap ran out of room. Please increase the size of APT::Cache-Limit. Current value: 123123. (man 5 apt.conf)

To fix this, navigate to /etc/apt/apt.conf.d and edit the file related to debconf which in my case was 70debconf. Add the following line to the bottom of this file and save it:
APT::Cache-Limit "200000000";

Error message: iptables-restore v1.x.x: no command specified

If you run into the following error message when attempting an iptables-restore < my.rules:
iptables-restore v1.4.8: no command specified
then the problem is that you have very likely just copied and pasted stuff into my.rules which has led to some dodgy line-breaks terminating blank lines in the file.

On a server I am working on right now, I installed a PHP application and attempted to run it. However, I ran into a "500 Internal Server Error". Upon further investigation by checking the logs, I found the following errors in the Apache error log:

Vim E303: Unable to open swap file for "[No Name]", recovery impossible

On a new installation of GVim (in Windows 7), I ran into the following curious error whenever I tried to open a new document for editing:
Vim E303: Unable to open swap file for "[No Name]", recovery impossible

According to friendly chap on IRC, this is caused by a temporary directory bug and that it can be fixed by adding the following directive to the _vimrc file:
set directory=.,$TEMP

MySQL charset issues while importing data using LOAD DATA INFILE

Submitted by Druss on Tue, 2011-09-27 20:47

Earlier today, I was banging my head against the wall trying to import some data in a CSV file into MySQL. While my imports have gone well thus far, this time around I was dealing with data involving lots of strange diacritics, runic squiggles and other manners of gibberish that make the world as fun as it can be. In other words, I was dealing with Unicode.

MySQL's LOAD DATA INFILE leads to an ERROR 29 (HY000) File not found / (Errcode: 13)

While trying to import a CSV file into MySQL today using the LOAD DATA INFILE command, I ran into the following situation:

mysql> LOAD DATA INFILE 'foo.csv' INTO TABLE bar FIELDS TERMINATED BY ',' ENCLOSED BY '#' LINES TERMINATED BY '\r' (a, b);
ERROR 29 (HY000): File 'foo.csv' not found (Errcode: 13)

The file exists fine and the permissions are also kosher. After much gnashing of teeth and perusing of documentation, I found out that local file sources require the LOCAL keyword:
