dpkg

[lina <lina.lastname@gmail.com>]

Hi,

I read the man dpkg,

and didn't think too much, just tried the

  dpkg --clear-selections

and then the dpkg --get-selections shows

root@Debian:/home/lina# dpkg --get-selections | grep deinstall | wc -l
2991
root@Debian:/home/lina# dpkg --get-selections | grep  " install" | wc -l
0


I feel I am in trouble again, don't know how to recover/restore.
kinda of very silly though, but is it very dangerous?

Thanks ahead,

Best regards,
