Sky Charts install

[billtour]

I'm trying to install Sky Charts (Carte du Ciel) in a new install of v.5.8 of L.L.  First of all, what should I look for in the long list of possible downloads of software? .Deb?  ,Tar? The .Deb seems to not get started installing.  The .tar tried .  I can supply error messages. Thanks for the help.

The line

Code:

gpg: no valid OpenPGP data found.

indicates your system wasn't able to import the public key required.

I'd suggest trying it again.  You should see a message including

Code:

gpg: key 8B8B57C1AA716FC2: public key "Patrick Chevalley <[email protected]>" imported

instead of the no valid data found message.

If it continues to fail we need to look at why your system isn't importing keys.

Same result two more times.  What next?  I'm clueless.  Thanks for the help.

What next?

I would look at the Sky Chart install script and break it into small steps to see if we can work out what is happening.
You appear to have a problem getting the key, so trying to do this step manually in verbose mode might show a problem.

The wget command below is a slightly modified line from the script.  It will try to get the key from the location specified in the Sky Chart install script and save it in your home directory. It has verbose options enabled.

Code:

wget -O testskychart.key "http://keyserver.ubuntu.com/pks/lookup?op=get&search=0x$key"

It may throw an error message so post back what happens.
If it works you can examine the resulting key file with

Code:

cat testskychart.key

You should see a block of apparently random characters bounded by

-----BEGIN PGP PUBLIC KEY BLOCK-----

-----END PGP PUBLIC KEY BLOCK-----

[billtour]

I didn't see any errors after running "wget".  However, "cat" gave me pages of what looks like what you might see when opening a non-text file using a text editor.  It was pages of mostly characters that look like question marks inside of diamond shapes.  I saw no "begin pgp public key block".  I hope this helps.

[stevef]

It does help a bit.  The key file should be a properly formatted, readable text file with definite, legible header and footer which is very different to the randomness of a non-text file.
So it sounds like something has gone wrong at that stage.

It might help more to see the actual text that you see on screen while executing the verbose form of the command.

Code:

wget -SO testskychart.key "http://keyserver.ubuntu.com/pks/lookup?op=get&search=0x$key"

[billtour]

The following is all of what comes up when I run the "CAT" command:

C�1~�*3WJ�%��~�g��o��NЃE��OYE��S�F�j}���*�}�9�"�L
H;��߆�د����Mގ���/

Edit - just showing a sample of output.

[stevef]

That's we'd expect from your earlier description. If you post what actually happens when you issue the verbose 'wget' command it might show why wget is not getting the key properly.

Code:

wget -SO testskychart.key "http://keyserver.ubuntu.com/pks/lookup?op=get&search=0x$key"

Thank you
