Cannot download some libs. #60

Open cccccyd opened 2 years ago

cccccyd commented 2 years ago

cccccyd@CYDsLaptop:~/LibcSearcher/libc-database$ ./download libc6_2.23-0ubuntu10_amd64 Getting libc6_2.23-0ubuntu10_amd64 Invalid ID, maybe the library was fetched in an older version or added manually?

It just says its an invalid ID, I don't know why this happened...

I noticed that some libs were not available on ubuntu mirror source. But I can find the right libc on https://libc.rip/. Maybe this site using the old version library of libc.

I'm running into a similar issue with libc6_2.27-3ubuntu1.4. I think the reason is because the URLs like http://archive.ubuntu.com/ubuntu/pool/main/g/glibc/ only contain the latest version of the package pushed to any release channel (i.e. updates, security, etc.). libc.rip probably has that libc because it's continuously downloading and storing each libc.

The thing is, we should still be able to download the old releases from launchpad, i.e. https://launchpad.net/ubuntu/+source/glibc/2.27-3ubuntu1.4. So the download script could probably be improved to do this.
