Incorrect URLs in pdf installation guide #40353
Description
Steps To Reproduce
Click on one of the 4 highlighted links near the bottom of page 12 of https://doc.sagemath.org/pdf/en/installation/installation.pdf. For example, Fundamental system packages required for installing from source.
Expected Behavior
An appropriate web page opens in the browser (or an appropriate pdf file is downloaded).
Actual Behavior
404 Error: File not found.
Additional Information
The problem was reported in this sage-devel thread.
Clicking on "Fundamental system packages required for installing from source" leads to https://doc.sagemath.org/pdf/en/reference/spkg/_prereq.html. The problem is that this is an hmtl file, so it is not in a pdf directory. A link that seems to work is https://doc.sagemath.org/html/en/reference/spkg/_prereq.html (but perhaps it would be better to link to a corresponding pdf file).
Environment
- OS: N/A
- Sage Version: 10.6
