Hi, I have had some trouble installing Sage 9.2 & 9.3 on my Linux Ubuntu system.

I couldn't find any other references to this build problem.

In April, I tried installing 9.2, and and it hung on rpy2 twice, but the 3rd time it worked OK.

I installed 9.3 in this month, and it hung twice. I decided to comment out or remove the rpy2 entries in the "configure" file, and the build was OK.

My Ubuntu system does not use "snap", otherwise generally normal.

I may have found the cause of the problems.

I saved the /tmp files from the build.

File pip-req-build-d0lh1wr4/rpy2.egg-info/requires.txt has content:

cffi>=1.10.0 jinja2 pytest pytz tzlocal

whereas pip-req-build-d0lh1wr4/setup.py has:

if __name__ == '__main__': pack_dir = {PACKAGE_NAME: os.path.join(package_prefix, 'rpy2')}

requires = ['jinja2', 'pytz', 'tzlocal']

So, pytest is missing.

Could anyone confirm this possible error, please?

Note the line Applying ../patches/setup-no-pytest.patch in the log file: this patch removes pytest as a dependency in rpy2's setup.py. So I don't know why it's in the file you quoted. On the other hand, you could try sage -i pytest to install that package and see if that helps with rpy2.

If you're not planning to use R at all, you can disable it in the build with a configure option:

$ make configure
$ ./configure --disable-r
$ make -s V=0  # or just `make` if you prefer verbose

Thank you, I will use the disable configure option.

I'll have a go at working out why it the build hangs, as well.

I hope you work that out and it can be fixed.

I installed 9.4 yesterday, with rpy2 hanging.

I didn't modify the configure, however I was "successful" using export MAKE="make -j4". I think this helped by leaving the rpy2 build running, but successfully running everything else.

The build seemed to have finished, with the last message:

[dochtml] Build finished. The built documents can be found in /media/kevin/KCY_Samsung_T5/Sage/sage-9.4/local/share/doc/sage/html/en/thematic_tutorials

I checked my "System Monitor", and there was about a dozen rpy2 tasks hanging, so I killed them. Sage and Jupyter worked OK.

I think the problem is rpy2 "requires" pytest, which doesn't seem compatible with Sage.

I'll keep looking.
