HELP ! URGENT!Package and update installation problem

Asked by Utkarsh Rao

Hi guys, whenever I try to install a package from the software center, or I try to install updates, an error pops up saying that "This installation requires the installation of untrusted packages" and closes. I have tried going into the settings and authenticating everything, to no avail. So far I have been unable to install anything. Please help! Thanks.

How is that urgent in ANY way! You just haven't added the GPG key for some repo you have added....

Not urgent whatsoever

can you give the output of:

uname -a; lsb_release -a; sudo apt-get update

Thanks

Um, I'm new to Linux so I have no clue what you just said. I haven't added any repos, I'm trying to install wine, and it's not letting me because of that authentication thing. The update worked though, thanks.

Copy the output and paste here as an update

E: Some index files failed to download, they have been ignored, or old ones used instead.
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

ok if you have software centre open then close it. If you have updates running then let them finish. You can ONLY have ONE app accessing the packages at any one time.

If neither of the above are happening then run:

sudo fuser -vki /var/lib/dpkg/lock;sudo dpkg --configure -a

To free up the packages.

Then rerun the command I gave

Thanks
