How to uninstall?

[nimaim]

I am on the latest Mint (21.2), but it should mimic Ubuntu versions of most packages except for snap which it does not install. Long story short, I had CAC auth working okay with Chrome prior for many years with cackey 0.7.11, but decided to give this script a try so I could get Firefox running and working with my CAC. Running this, everything seemed to install just fine (no errors), but now my smart card reader (the very popular SCR3500) seems to flash 3 consecutive red lights indefinitely and hangs on any interaction with the CAC. When you plug it in with no browser open, it will not flash any lights, but as soon as you open FF or Chrome, it will start doing that 3 light pattern and no CAC enabled site will work; rather, it seems to just hang until you take the CAC out, at which point obviously any validation will fail.

Since I have no idea how to even begin troubleshooting this, is there any way to uninstall this? I'd like to undo everything the script has done and start over with the manual procedure and get back up and running as I use this laptop for work daily. One bug I did notice is it started installing certs to any folder named .pki/nssdb (including in all my cross compiled distros I use to test on diff SBCs at work) instead of just the current $HOME, so I am not sure if that contributed to this problem. Thanks.

My apologies for the delay. It is unlikely that the DoD certs being present in the other NSSDBs caused an issue with your CAC reader. It seems more likely that either the middleware or cackey caused this issue. You could try simply removing cackey and trying opensc using the following commands:

sudo apt remove cackey
sudo apt install opensc
reboot

The reboot is only necessary to allow opensc to write the proper configuration to all of the different pkcs11.txt files, which it does automatically upon reboot.

To answer your original question, the script installs the following (providing the full command):

apt install -y libpcsclite1 pcscd libccid libpcsc-perl pcsc-tools libnss3-tools unzip wget

You would need to add cackey to this list, which I install manually to hold to a specific version. Simply running the following will remove all of these tools (remove anything that you would like to keep):

sudo apt remove cackey libpcsclite1 pcscd libccid libpcsc-perl pcsc-tools libnss3-tools unzip wget

While these shouldn't affect much, you will also want to remove the following lines from any pkcs11.txt file for a full purge:

library=/usr/lib64/libcackey.so
name=CAC Module

Please let me know if I can help in any other way.
