Dear Maintainer,
while working on the Kali Linux installer (which is just the Debian
installer with minor modifications), I hit a bug in apt.
The logs I get from the Kali installer go like this:
base-installer: Writing new source list
base-installer: Source list entries for this disc are:
base-installer: deb cdrom:[Kali GNU/Linux rolling ...]/ kali-rolling main
base-installer: Repeat this process for the rest of the CDs in your set.
base-installer: E
base-installer: :
base-installer: Cannot convert 2538832704 to integer: out of range
base-installer:
base-installer: error: error while running apt-cdrom
The error 'Cannot convert ...' comes straight from apt [1]. The number
2538832704 is the size of a very big package in Kali. It's above MAX
INT, so I suspect that somewhere in the apt code, we try to parse Size
as an integer, instead of using a type unsigned long long.
After some more research, I found it:
apt-pkg/indexcopy.cc
----
bool PackageCopy::GetFile(string &File,unsigned long long &Size)
{
File = Section->FindS("Filename");
Size = Section->FindI("Size");
if (File.empty() || Size == 0)
return _error->Error("Cannot find filename or size tag");
return true;
}
This `FindI` should really be `FindUUL`.
A patch is on the way.
Thanks,
Arnaud
