Problems with PPA repositories

I'm running ubuntu 12.04 and i'm having problems with PPA launchpad repositories: i add them using the command

Code:

sudo add-apt-repository ppa:.....

and everything works fine, but then with a

Code:

sudo apt-get update

I get hash mismatch errors.

Code:

......

bzip2: Data integrity error when decompressing



.....



W: Failed to fetch gzip:/var/lib/apt/lists/partial/ppa.launchpad.net_xxxxxxxxxxx_ubuntu_dists_precise_main_binary-amd64_Packages  Hash Sum mismatch

If I browse the PPA folders with Firefox and manually download the package file, I can expand it and read it with a text editor. I even tried copying it into /var/lib/apt/list and it is recognised by the synaptic (i.e. I can download listed packages). Problem is, the file automatically retrieved by apt-get and available in /var/lib/apt/list/partial is indeed corrupted and its size is different from what I manually download.

What is wrong ?

thanks in advance

Does the PPA have it's own instruction on how to add it? If it does try that method, maybe even add it manually and then try apt-get update.

Actually after a long googling session and found a similar but seemingly unrelated problem with PPA's. Solution to that problem is to add in /etc/apt/conf.d a file named "99<whatever you want>" containing a simple line of text:

Code:

Acquire::http::Pipeline-Depth "0";

That has fixed my problems with http PPA's (the vast majority) but indeed I now have problems with ftp PPA's (like the one I used before...)

cheers
