Update: The following packages have been kept back ???
 
Yesterday, while updating a 32 bit Lucid desktop using update manager, I noticed that only one of several packages listed under "Important Security Updates" was checked. I ran "Install Updates" and the one package was installed. The others were now grayed out and I could not check them. It was late so I put off investigation until today.

I am now working on my 64 bit Lucid desktop. Same thing. Only one of several packages is checked. I tried using "sudo apt-get upgrade" and received the following message:
Quote:

The following packages have been kept back:
ffmpeg libavdevice52 libavfilter0 libavformat52 libpostproc51 libswscale0
I thought perhaps the packages were held back because I did not have them installed. Not so. I have these packages installed. I am at a loss. If these are important security updates, why am I not able to install them?

TIA,

Ken

Hi,

As I understand it, some packages are held back by the package manager because they would implicate system changes. You can force them/install them and apply the changes using:
Code:

sudo apt-get dist-upgrade
Kind regards,

Eric

If you use upgrade instead of dist-upgrade all package-updates which will force the deletion (not upgrade) of an installed package or the installation of a currently not installed package will be kept back. As mentioned above, if you want to install them, use dist-upgrade.

Thanks all, I did some research into the dist-upgrade option. But then other obligations took me away before I actually ran the upgrade. This morning update manager popped up and offered to install all of the packages which were held back yesterday. Who knows?

Thanks again,

Ken

Hi,

Most likely because overnight the system changes where / would be included automatically by upgrading other packages. Glad you've got it solved. Have fun with Linux.

Kind regards,

Eric
