How do I list all packages installed for a specific architecture?

Question

I want to list all the packages installed for a specific architecture, in this case i386, and if possible, install the package from another, in this case amd64. How would I go about doing this?

Answer 1

To find the packages of architecture i386, you could filter the output of dpkg -l, where lines that start with ii, and column 4 is i386:

dpkg -l | awk '/^ii/ && $4 == "i386" { print }'

To install the package of the amd64 architecture, you could use :amd64 suffix of the package name with the install command.

Answer 2

You can use apt list as well as dpkg-query --list to get installed applications.

Use man apt and man dpkg-query to find what other functions it has.
