While checking the status of packages using dpkg, you may come across the state rc.
$ dpkg --list Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Description +++-===============================================-===============================================-============================================ ii acpi-support 0.136 scripts for handling many ACPI events ii acpid 1.0.10-5ubuntu2 Advanced Configuration and Power Interface e ... pn dvipdfmx 1:20090115-1.2 A DVI to PDF translator with CJK support ii e2fslibs 1.41.11-1ubuntu2 ext2/ext3/ext4 file system libraries
What does pn mean?
For detailed information on interpreting the status, you can refer State of a Package. pn corresponds to
- p: the package was marked for purging
- n: the package is not currently installed in the system
In nutshell, it means that the package is completely removed (even the configuration files). Read dpkg: purge versus remove
