How do I update packages that have been held back?
When I run
apt-get update and
apt-get upgrade it does not upgrade. Here is what I see
Reading package lists... Done Building dependency tree Reading state information... Done Calculating upgrade... Done The following packages have been kept back: tshark ubuntu-minimal wireshark wireshark-common 0 upgraded, 0 newly installed, 0 to remove and 4 not upgraded.
What's going on?
The message that you are seeing indicates that one or more dependencies of the installed packages listed in the message have changed. APT assumes that you would rather review the changes before applying them, and so the affected packages are listed as "held back". To proceed with updating the packages, you can try updating with the following command:
sudo apt-get --with-new-pkgs upgrade
If that does not work, then you can try installing the updated packages manually:
sudo apt-get install tshark ubuntu-minimal wireshark wireshark-common
I also found this post, which indicates that using
apt instead of
apt-get should allow the packages to update, despite the change in dependencies.
