Dear Trisquel users,

Through regular update, I got the warning that the update of libplist1 can't be verified.
I don't think I need the program, but if I want to remove it, a lot of core functionality, including KDE and triskel-recommended would automatically be removed from my system.

Thank you.

Have you try:

sudo apt-get update

You can also use synaptic on system settings and use "Reload".

That might solve the "can't be verified" problem.

sudo apt-get update
-> nothing
sudo apt-get upgrade
-> there it is, libplist1

I've now upgraded it.
But still think it is IMHO peculiar that the package is not normally removable.
If a package can't be verified something is wrong, isn't it?

Thank you.

Did it still gave you the same error after doing "apt-get update"? It's weird. As far as I know all what it means is that the source of the package (where is it coming from) can not be verify, which means that some one could be trying to fool your system to think that you are receiving the package from trisquel but you are not, and instead you end up installing malware.

This isn't usually the case though. I don't know much about certificates to tell you the true, but things like your system time and date being wrong can cause problems with the verification. Most other problems get fix with "apt-get update" in my experience. Some times waiting an hour also help.

Did you have other packages that needed an upgrade? Do those packages didn't give you problems? Usually all packages coming from the same source would give you problems if there are difficulties verifying the source. Maybe you have add other repositories? You can check where the system got the package by going to the package properties on synaptic.

If you didn't added other repositories I wouldn't worry too much if you already upgraded it. I haven't hear of any trisquel user been attack through package upgrading, and most of the time it's just an error with the verification process. It's better to be safe though.

Try to install anything else coming form trisquel's repository and see if it gives you any error. It can be anything like a game called Magicor that I love so much. Then if one step before you install it it gives you also the same error, post the entire output to see if some one in the forum can help.

Thank you. I now ignore messages from "Muon software center" and just update and upgrade through terminal and synaptic.

Thanks for posting this problem because I get the same message for any repository app I attempt to install.
So you are not alone with this.
