[SOLVED] TERM environment variable not set in Guake

After upgrading to Maverick Meerkat yesterday, my Guake terminal started giving the following error on executing top:

TERM environment variable not set.

You can fix the error by doing exactly what error says – set the TERM variable. To do that execute the following in terminal:

echo -e "TERM=xterm\nexport TERM" >> ~/.bashrc

Kill the guake terminal

kill -9 $$

You don’t need to run guake again, just press your keyboard shortcut to bring back Guake and it will appear. Now you can execute commands as normal.


[SOLVED] Error ‘dpkg: error processing <filename> (--unpack) trying to overwrite…

Recently I got this error after installing VLC on Ubuntu 10.10 Maverick Meerkat. Not really remembering what caused the error to be triggered in the first place, it became very difficult to find a solution for it.
When I executed sudo apt-get upgrade to upgrade my packages, it told me there was some issues and I needed to execute sudo apt-get -f install to fix them. I did as advised but it produced the following error:

After some time of googling and head-scratching, I finally found a solution and it wasn’t that difficult either.
To fix it just note down the path of files which are causing the trouble. From the above mentioned error, we can clearly see that there are these two files causing the error:

[SOLVED] ‘Can’t connect to local MySQL server through socket’ error

Yesterday I got the error:

ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’ (2)

when I ran the command mysql through terminal in Ubuntu 10.10

This error can also be linked to error in phpmyadmin:

Connection for controluser as defined in your configuration failed.

I figured out it was due to mysqld not running. I simply did

sudo /etc/init.d/mysql start

to start mysql daemon. This solved the error.
