Apps :: Problems installing browser update

Just about a week ago I installed Opera 9.22 without problems.
Now I'm trying to install the update (9.23) and just can't remember how I did it the last time.
The download comes as a .tar.gz file.
So, I unzipped it (gunzip) and then untarred it( tar xvf) and CDed into the resulting directory.
Here I tried dsl-dpkg.dsl which gives a "command not found error" (although I had just downloaded this).
Then I tried "install.sh" and it started off fine but stopped after a few lines complaining that I didn't have write permssion for some directory or other.
So, then I tried "sudo install.sh" and this time I get a "no such file or directory error".
I know this has to be simple but the solution is eluding me.
Please help

Well, I finally got the update installed by using dpkg -i on the .deb file version of the download.
Strangely, I'm sure I used the .tar.gz the last time but I really cannot find how to install this.
Although I don't need this urgently, it would be good to know what I overlooked.
Thanks

You don't need to install it, just untar it whereever you need and launch opera with "opera" in the unpacked dir..

Ah, OK.
That might explain why the "dpkg -i" that I did on the .deb package seemed to finish in 1-2 seconds when in Ubuntu it might take 10-20 seconds.
Perhaps the untar that I had already done was the real reason that Opera 9.23 became available to me.
Thanks for the clarification
