[jrmchess]

I get this error
E: GPG error: http://deb.torproject.org precise Release: The following signatures were invalid: NODATA 1 NODATA 2

whenever I run this command:

sudo apt-get update

I want to install the below software but always fail to do so:

1. ubuntu tweak
2. a world clock
3. vb6 to run excel macros

I am really feeling frustrated using ubuntu and thinking of reverting to windows but I don't want to. Someboby please help me. Thanks

You problem is that the GPG key for the repository http://deb.torproject.org precise Release you have added is incorrect.

Please, see this thread: http://ubuntuforums.org/showthread.php?t=2053051 with workarounds and explanations why you obtain the GPG Key error.

I am not sure what causes that error but a possible fix is to enable 'Source code' in 'repositories'.

Open Software Center-> Edit -> Software Sources -> enable (check) 'Source code'.

Then:

sudo apt-get update
sudo apt-get upgrade

Try changing the 'Server' to 'Main' in 'Software Sources' and try 'sudo apt-get update' again.

If that doesn't help either then try:

sudo apt-get install deb.torproject.org-keyring

I changed the server to main but got the this error,

E:GPG error: http://deb.torproject.org precise Release: The following signatures were invalid: NODATA 1 NODATA 2

I then did sudo apt-get update and got

My friend today told me that he had tried changing some settings some days back to install the tor browser on my computer but was unsuccessful. He realised this when I showed him your post containing
sudo apt-get install deb.torproject.org-keyring. He doesn't remember what settings he had tried to change but he is sure he followed exactly what was there on this site: http://nithinaneeshsct06bt.blogspot.ae/2012/07/installing-vidalia-tor-in-ubuntu-1204.html

Now I am too afraid to touch any of those settings. Can u please advise me what I can do to revert back? Thanks

[jrmchess]

can anyone help me please? Thanks

For now, disable 'torproject' repository. You can do this from either 'Software Center' or by editing the above file directly...
'Software Center-> Edit-> Sources -> Other Software -> uncheck/deselect

deb http://deb.torproject.org/torproject.org precise main
deb-src http://deb.torproject.org/torproject.org precise main

Run:

sudo apt-get update && sudo apt-get dist-upgrade

yes I have already tried this and it resolved the issue. Thanks

[fantab]

If you have disabled 'tor repository' and have 'tor' installed then you will not get any updates or fixes for it. The above is only a temporary fix....

Hello,

I had the same problem with the OP, receiving the messages NO DATA 1 NO DATA 2 and similar.

I changed servers, repositories, I downloaded other keys, changed the sources.list file under the /etc/apt
to no avail.

Sometimes I was able to see that it started loading, yet sooner or later it stopped reporting this issue.

I order to solve it at that box I was (using wubi), the system administrator had to change some firewall options in order not to keep blocking the apt-get command.

Hope it helps for future reference,
Regards!
