Ubuntu Installation :: Medibuntu Update - Signatures Were Invalid
Jul 6, 2010
I was doing an update today and got the following error:
W: GPG error: [URL] lucid Release: The following signatures were invalid: BADSIG 2EBC26B60C5A2783 Medibuntu Packaging Team <firstname.lastname@example.org>
I have tried updating the keys, and got this:
apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 2EBC26B60C5A2783
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /etc/apt/secring.gpg --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --recv-keys --keyserver keyserver.ubuntu.com 2EBC26B60C5A2783

gpg: no ultimately trusted keys found
gpg: Total number processed: 1

When I go to the Update Manager to update my system I get the following error message: W: GPG error: http://packages.medibuntu.org lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 2EBC26B60C5A2783
I am not sure what this exactly means and what I need to do to fix this.
I keep getting this error whenever I try to update or reload. Does anyone know how to get rid of this or fix it?

When you add medibuntu to 10.04, isn't there supposed to be a "medibuntu" sub-category on the left side? I installed the medibuntu repo expecting that I'd find google earth in there. But when I added it, I didn't see it listed there - even after rebooting.
This has to be the sixth time I am going to have to reinstall Ubuntu (Can't get enough of that Linux greatness) in the past 6 months. I just don't understand what exactly is wrong, I don't install anything extra (but the ubuntu restricted extras) yet updates that ask me to reboot will take me to a GRUB command line screen and trying to boot through the command line interface gives me an, "Invalid Magic Number", error.
There should be an official tool for when problems like this come up, so that users like me can easily move their files off their HDD before reinstalling. I didn't come here to rant but, does anyone know what may be causing this everytime, how it can be avoided maybe even how to deal with the Magic Number error and boot in (I wouldn't mind typing in the commands every time BTW)?

I'm following the instructions in the Medibuntu wiki. When I run the command in the terminal to add it to the repository, it runs for a couple of minutes then gives this error: Code:W: GPG error: URL...The following signatures couldn't be verified because the public key is not available: NO_PUBKEY BE1B248616AE4E77.What does that mean, and how can I fix it?
I recently discovered the medibuntu repository and wanted to add the repository to synaptic. I copied and pasted the code from this: [URL] web page on medibuntu.org's website.
The attachment shows exactly what the terminal spit out after running this command (and the command that was run - of course). What I am wondering about is the last six lines - which seem to indicate that, at a minumum, getting some key was not successful. I'm not sure how important this is; but, since I don't actually have anything I need to install from this repository right now, I wanted to be sure I'm squared away for when a time may come in the future.
After running the command I did the following to try and determine the status:
I went into synaptic > settings > repositories and looked under two of the tabs to see what was there:
The tab, "Other Sortware" Lists two entries at the bottom that stood out to me. They are:
Medibuntu - Ubuntu 11.04 "natty narwhal" (http:// packages.medibuntu.org/natty free non free) which was checked.
Medibuntu (Source) - Ubuntu 11.04 "natty narwhal" (http:// packages.medibuntu.org/natty free non free) (Source Code) which was not checked.
The tab, "Authentication" lists a total of three entries. Their descriptions are:
Ubuntu Archive Automatic Signing Key
Ubuntu CD Image Automatic Signing Key
Ubuntu Extras Archive Automatic Signing Key
None of those (under this Authentication tab) strike me as having anything to do with medibuntu (could be wrong though - just not sure).
Finally, I did a search in synaptic for a library I think should be available through medibuntu, "libdvdcss." I was presented with a list of eight items, none of them matching libdvdcss by title. The closest match by title and description that I could identify was, "libdvdread4" This I did as a sort of test to see if I might be accessing that repository.
What's the point of checking if my file was tampered (as it says in the debians page [URL] ....) if the signatures are downloaded over http? Didn't the recent incident with Linux Mint had cleared our mind about these things?
Bottom Line: Dvd Drive died in my toshiba laptop and it was replaced (not before tech for some reason reformatted the Win7 partition... which was 100% un-needed, but thats beside the point now. I redid win7 (the tech installed vista) and am TRYING to "redo grub". Facts: The Slackware AND Ubuntu Partitions ARE STILL THERE and when i use SuperGrub Boot CD (which doesn't restore my grub by itself) to boot into slackware, i can see ALL THE CONTENT of both Linuxes still there including grub on ubuntu partition
(Tri-Boot: Ubuntu, Slackware, and WIn7) I had it working for two years or so, SO i know this "setup" works fine. I am A) Trying to do this as simply as possible. B) Trying to avoid the need to download a 800MB ISO (as seen for this issue on this forum) and trying not to have to reformat Ubuntu Partition (though I have the .Debs I have downloaded for it backed up ... all 1.7GB of them) I have /dev/sda1 as win7, /dev/sda2 as Slack and /dev/sda3 as Ubuntu (which contains Grub Legacy).. Every command I do seems to result in an error like "invalid command" or "invalid Execution format " (i think that second one is right) type errors. I compiled (awhile back) a few kernels for Slackware, but feel goofy that I cant figure what i this out (what i thought was going to be a "2 minute" fix)
I updated my system from FC13 188.8.131.52-66 to 184.108.40.206-68 for both the kernel and the kmod-wl RPM's. After doing so, iwconfig wlan0 key 1234567890 no longer works. I get an error indicating 'invalid argument'. If I reboot using the previous kernel/wl.ko module, it works The size of the wl.ko module increased in size by almost 30%. Did I somehow get the wrong RPM?
I have a GnuPG key that's been signed by several people. I want to add another name (and e-mail) to it.I used seahorse to do it, but it doesn't look like the old signatures migrated to the new name.Is this standard behavior? Is there a way that I can migrate the signatures, or do I have to request that the signers themselves do it?

I'm trying to update Karmic to Lucid. I try to update Karmic to the most recent update before I upgrade I get this error. W: GPG error: [URL] karmic Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 5A9A06AEF9CB8DB0
I upgraded a machine from 9.10 in the hopes that 10.04 will have fixed the audio problems that were present in the 9.10 installation -- the problem being that I have no audio. When I check the pulseaudio volume meter, it shows audio present in both channels. I've not been able to find anything where a mute button is checked.
Thinking it might be a codec, I tried to reinstall Medibuntu. I get the error message: unable to lock /var/lib/dpkg. Is another process using it. I've done a "ps -ef" looking for a process that might be causing problems, but no luck. I'm using an Intel ICH5 audio board -- if I'm reading everything correctly.
Sorry for the multiple headings, but I thought they might be inter-related. What I'd like: audio playback from an on-line source (Hulu.com). Ideas on how to make that happen will If medibuntu isn't part of the problem, just let that slide by, and I'll post a separate help "request" later.
Want to install new one from Medibuntu repository. I have issued command on [URL]
Is there a command which display the repository of given archive (which will be installed) ? I wan to ensure that future installed ffmpeg will be installed from Medibuntu and not from some other repository.
I installed Debian 5.03 Lenny successfully on my machine. I got this error during boot: ACPI : invalid PBLK length . After that the Operating System boots properly and starts normally. What does this error statement mean? Is it safe to work with this installation despite this error?
Trying simply to insert into table. Have succeeded in doing this but now want to correct user use of invalid characters. If I'm understanding correctly, Real-escape-string seems to correct these, so I've been trying to figure out how to use it. A short, test code version gives me a syntax error at INSERT VALUES, which--because it still has the single quotes in the text--tells me the real-escape-string didn't work. The code below gives me a parseing error with invalid $END at </body>.
Insert Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' VALUES (UTC_TIMESTAMP,'What's happen' bra?')' at line 1 Parse error: syntax error, unexpected $end in /home/powere15/public_html/DB/exercises_insert_record.php on line 94 <html><head><title>Exercise Catalog Insert Record</title></head> <body> <? /* Change db and connect values if using online */ [Code]....
My software sources some how got screwed up. Now when I try to install from software manager or Synaptic, I get error messages. Here is the error messages at the bottom of "sudo apt-get update" :
W: GPG error: http://archive.ubuntu.com lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 40976EAF437D05B5 W: GPG error: http://archive.canonical.com lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 40976EAF437D05B5
I had my Logitech Webcam/mic working perfectly, in 8.10, but when I upgraded to 9.10, the video stopped working. The camera works in lots of other software,Cheese to luvcview to testing with gstreamer-properties But Skype's video crashes when I try to use the video camera. Usually a segmentation fault.
Lots of other threads here suggest that using the version of skpye packages in medibuntu is the solution. So I added medibuntu to my /etc/apt/sources.list, reloaded to get the latest directories. I don't see any "skype" to install, either in Synaptics or in the shell with apt-get Output from apt-cache search is
# apt-cache search skype skytools - Database management tools from Skype to PostgreSQL python-skype - Skype API wrapper for Python skysentials - extra functionalities for Linux Skype client skype-mid - Skype for MIDs
p.s. any one have clues as to why this broke going from 9.04 to 9.10?
