Uninstalling Google packages from Ubuntu

So, you installed an app from Google (Chrome or Google Music Manager) but are done with it and now you want to remove any traces of the Google software…
You’d think that sudo dpkg -p <packagename> would do it but Google’s a little more sneaky than that… They took the liberty of adding their repository to your machine. To remove it you need to perform the following steps.
sudo rm /etc/apt/sources.list.d/google-musicmanager.list
sudo apt-key del linux-packages-keymaster@google.com

As a side note, it doesn’t seem right that they add the repository settings with a cron job instead of at the install of the package. It seems fishy to me because if you remove their repository settings without disabling their cronjob, their settings will come back the next day. Check out /etc/cron.daily for any google files before you uninstall their package to see what they are up to.

Error/Fix: Disable byobu (screen) from automatically starting on login (EC2)

Error:
If you run Ubuntu 11.10 (Oneiric Ocelot) on Amazon EC2, you may notice an annoying “feature” that they enabled on this release. A byobu session is started when you login.

Fix:
Fortunately, this is easy to fix:
rm /etc/profile.d/Z98-byobu.sh

Note:
Also fortunate, this will not be the case for future releases as it has been removed.

“Could not read chunk size:” error when checking out from subversion

I recently ran into this error part way through when checking out a large repository from subversion:

svn: REPORT of '/svn/!svn/vcc/default': Could not read chunk size: connection was closed by server (http://some.hostname.com)

Since it was a rather large repository, I’m guessing it is the size of this checkout process causing the problem. Fortunately, the fix is easy. You just have to go into the directory with the partial checkout and run ‘svn up’ In my case, I had to run it two more times to get the entire repository.

Phone Phisher

Just had a phisher call me claiming to be from the US Bank fraud dept (caller id said 714-555-1212.) I don’t have any credit/debit cards with them. It was a computer generated recording saying my account was frozen and they needed to verify some of my information to unfreeze it. Unfortunately, it wouldn’t accept my made up account number.

Just remember, if you ever have someone call you asking for information like that immediately hang up and call the company in question directly, using a phone number you know is really theirs. Caller ID can be easily faked, so don’t depend on it to authenticate a caller either.
