.deb package has unknown libc dependency

[AndySchroder]

I've run ./scripts/build.sh debian to create lpac-2.0.1-Linux.deb. It looks like it will install one file, lpac.

$ dpkg -c lpac-2.0.1-Linux.deb 
drwxrwxr-x root/root         0 2024-05-29 13:11 ./usr/
drwxrwxr-x root/root         0 2024-05-29 13:11 ./usr/bin/
-rwxr-xr-x root/root    148920 2024-05-29 13:11 ./usr/bin/lpac
$ 

It also lists a dependency of libc

$ dpkg -I lpac-2.0.1-Linux.deb

When I try to install, it errors out because the libc package can't be found.

$ sudo dpkg -i lpac-2.0.1-Linux.deb

If I try to manually install libc, that also doesn't work.

$ sudo apt install libc

This may mean that the package is missing, has been obsoleted, or
is only available from another source

However, it did install the file lpac

$ which lpac 
/usr/bin/lpac
$ 

and it seems to start up okay

$ lpac 
SCardEstablishContext() failed: 8010001D
APDU driver init failed
$ 

I'm not sure what the libc dependency is about. Is it really needed? Is there a different package that should be referenced instead?

This issue is fixed by #106 . Please close after it has been merged.

It should be libc6.
