Greetings from Mexico City!

I am newish in the Linux world (Ubuntu 9.10).

I've been trying to install MikTex without success. The .deb files inevitably lead to an error (system feedback rather uninformative). I next tried to compile the source code I downloaded from the MikTex web page. I untarred it and ran the following commands with no errors:

cmake -G "Unix Makefiles"
sudo make install
sudo initexmf --admin --configure
But when I get to the next command:

sudo mpm --admin --update-db
the machine responds with a puzzling

mpm: LZMA decoder error.
Forum threads offer little information on this.

I will be grateful for clues...
