Search for and install packages

A Beckhoff RT Linux^® installation contains the required software for the operating system and the TwinCAT 3 runtime. You can install additional software or TwinCAT Functions. This chapter shows examples of how to search for TwinCAT packages and then install them. The command line commands can also be transferred to other packages.

You can use this command to search for all packages that contain the term "TwinCAT":

apt search TwinCAT

For example, to search for a specific TwinCAT function, you can use the following command:

apt search tf5000

The system searches for the specified character string (tf5000) or the specified regular expression in the package name and the short description. This is not a "fuzzy" search (similarly spelled words will not be found automatically); it is a substring/regex match. This command is used to find packages which have the character string somewhere in the package name or in the short description.

Then install the found package (tf5000-nc-ptp-xar) using the command:

sudo apt install tf5000-nc-ptp-xar
