I ran "make" again after running the command you provided. The error below still occurred.
I could not install several packages using "apt-cyg". Some packages could not be found, and some packages are not of the same build or version (e.g. apt-cyg install python3 -> python 3.9, not python 3.10 as used by "make").
Here is the full list of packages that I could not "apt-cyg install": (I also ran the 2 install command provided by the hints)

hint: installing the following system packages, if not
already present, is recommended and may avoid having to
build them (though some may have to be built anyway):
first install apt-cyg from
https://github.com/transcode-open/apt-cyg $ apt-cyg install libgsl-devel liblapack-devel libopenblas python39-devel R libtirpc-devel singular-devel singular libsuitesparseconfig-devel
configure:
hint: installing the following system packages, if not
already present, may provide additional optional features:
first install apt-cyg from
https://github.com/transcode-open/apt-cyg $ apt-cyg install lib4ti2_0 lib4ti2-devel libisl-devel graphviz texlive
configure:
hint: After installation, re-run configure using:
$ ./config.status --recheck && ./config.status
```

***************************************************************
Error building Sage.
The following package(s) may have failed to build (not necessarily
during this run of 'make all-start'):
* package: python3-3.10.3
last build time: Jul 21 08:52
log file: /home/Lucas/sage/sage-9.6/logs/pkgs/python3-3.10.3.log
It is safe to delete any log files and build directories, but they
contain information that is helpful for debugging build problems.
WARNING: If you now run 'make' again, the build directory of the
same version of the package will, by default, be deleted. Set the
environment variable SAGE_KEEP_BUILT_SPKGS=yes to prevent this.
