dselect is an old tool. Prefer other PackageManagementTools
dselect was the primary user interface for installing, removing and managing Debian packages. It is the traditional front-end to dpkg.
dselect allows more control over package management than using apt-get. In particular, when there is more than one way to satisfy a dependency, it lets you choose which to use.
E: Could not open lock file /var/lib/dpkg/lock - open (13 Permission denied):
An attempt is being made to run more than one package management process. This error may occur if an attempt to run more than one package management process is made. For example, if a package is being installed or removed using apt-get, or dselect, it should not be possible to run another package management tool, until the package updates are complete.
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?:
This error may also occur if a non-privileged (non-root) user attempts to install packages, or make a change to package status information within the package database.
