Ubuntu的存储库包含多少非免费软件？

Question

Debian的文档确实提到：

请注意，非免费和控制包的数量是less的2%的主要软件包。

Debian有三种存储库组件：main (包括100% 自由软件s)、contrib (包括依赖于非自由软件的免费软件)和非免费(包含专有性软件)。因此，文档是说，不到2%的主包包含在非免费和控制存储库中。

对于Ubuntu我也想知道同样的事情。Ubuntu在主和宇宙存储库和受限和多体存储库上都有免费软件，存储库的组件包含非自由软件。

现在，与主存和宇宙储存库相比，这些受限和多元的软件包含了多少非自由软件？我们有这样的分析吗？

虽然我没有在Ubuntu的文档中找到这样的信息，但是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 /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 %
