I am new to Linux and have been pounding my head against a wall for the last 2 hours


I installed Lubuntu onto my laptop and am trying to get a couple of packages for the use of a CAC reader.








using “sudo apt install” I was unable to get these files.


I searched the first one being pcsc-lite and found this website: https://launchpad.net/ubuntu/+source/pcsc-lite


when trying to figure out how to get the right package from that page installed the website keeps talking about PPA and other things but I can’t find anything like that from this page.


please help!

First, post the complete output of the apt install command. Copy and paste it her (in code tags), including the command you've typed.


One possibility is that  you have not synced the apt database (with apt update) before running apt install. Another alternative is that your apt mirror sources are misconfigured for some reason. A third possible reason is wrongly configured network (or some network error anywhere from your computer to the mirror). Or, possibly, those packages with those names just don't exist (I didn't check). Apt should give reasonably sensible error messages which should hint at what is wrong, but there is no way for anyone here to know unless we can see the output. For an introduction to apt, see: https://help.ubuntu.com/community/AptGet/Howto.


You need to run apt update and apt upgrade periodically (see "Maintenance commands" in the page I've linked above). If you don't, 1) apt could try to download old packages which don't exist anymore on the mirrors if your metadata (updated by running apt update) is not in sync or 2) fail because of unresolved dependencies, if upgrade hasn't been done recently enough.


As for PPAs, look here for a quick explanation: https://help.ubuntu.com/community/PPA
