Ubuntu 的存储库包含多少比例的非免费软件？

Debian 的文档确实提到：

请注意，非免费和贡献包的数量是少于 2%主要软件包的。

Debian 有三个成分存储库：主要的（其中包括 100%免费软件s),贡献（包括依赖于非自由软件的自由软件）和非自由（其中包含所有权软件）。因此，文档表明，不到 2% 的主要软件包包含在 non-free 和 contrib 存储库中。

我想知道 Ubuntu 的相同情况。Ubuntu 上有免费软件主要的和宇宙存储库和受限制的和多元宇宙 成分存储库包含非自由软件。

现在，与主存储库和 Universe 存储库相比，这些受限存储库和 Multiverse 存储库包含的非自由软件百分比是多少？我们有这样的分析吗？

虽然我在 Ubuntu 的文档中没有找到这样的信息，但我创建了一个简单的脚本来手动计算它：

#!/bin/bash

ubuntu_main=$(lynx -dump http://archive.ubuntu.com/ubuntu/dists/focal/main/binary-amd64/Packages.gz | grep ^Package: | wc -l)
ubuntu_universe=$(lynx -dump http://archive.ubuntu.com/ubuntu/dists/focal/universe/binary-amd64/Packages.gz | grep ^Package: | wc -l)
ubuntu_restricted=$(lynx -dump http://archive.ubuntu.com/ubuntu/dists/focal/restricted/binary-amd64/Packages.gz | grep ^Package: | wc -l)
ubuntu_multiverse=$(lynx -dump http://archive.ubuntu.com/ubuntu/dists/focal/multiverse/binary-amd64/Packages.gz | grep ^Package: | wc -l)

percentage="($ubuntu_restricted+$ubuntu_multiverse)/($ubuntu_main+$ubuntu_universe)"

echo "Total number of packages on Ubuntu's main repository = $ubuntu_main"
echo "Total number of packages on Ubuntu's universe repository = $ubuntu_universe"
echo "Total number of packages on Ubuntu's restricted repository = $ubuntu_restricted"
echo "Total number of packages on Ubuntu's multivrese repository = $ubuntu_multiverse"

echo "Percentage of non-free packages on Ubuntu's repositories= $(echo $percentage*100 | bc -l) %"

输出：

$ ./sample 
Total Packages on Ubuntu's main repository = 6090
Total number of packages on Ubuntu's universe repository = 53206
Total number of packages on Ubuntu's restricted repository = 143
Total number of packages on Ubuntu's multivrese repository = 813
Percentage of non-free packages = 1.61225040474905558500 %

对于 Debian GNU/Linux：

$ cat sample 
#!/bin/bash

debian_main=$(lynx -dump http://ftp.debian.org/debian/dists/buster/main/binary-amd64/Packages.gz | grep ^Package: | wc -l)
debian_contrib=$(lynx -dump http://ftp.debian.org/debian/dists/buster/contrib/binary-amd64/Packages.gz | grep ^Package: | wc -l)
debian_nonfree=$(lynx -dump http://ftp.debian.org/debian/dists/buster/non-free/binary-amd64/Packages.gz | grep ^Package: | wc -l)

percentage="($debian_contrib+$debian_nonfree)/($debian_main)"

echo "Total number of packages on Debian's main repository = $debian_main"
echo "Total number of packages on Debian's contrib repository = $debian_contrib"
echo "Total number of packages on Debian's non-free repository = $debian_nonfree"

echo "Percentage of non-free packages on Debian GNU/Linux = $(echo $percentage*100 | bc -l) %"

$ ./sample 
Total number of packages on Debian's main repository = 56873
Total number of packages on Debian's contrib repository = 293
Total number of packages on Debian's non-free repository = 602
Percentage of non-free packages on Debian GNU/Linux = 1.57368171188437395600 %

注意：本次分析不考虑更新和反向移植存储库
