2020-02-15 05:32:26 +0200	commented question	Sage 9.0 build fails at the sagelib step Thank you for your reply. The root cause appears to be some patches that was applying to it that I thought were necessary but turns out weren't needed. In addition, the SlackBuilds script looks like it was updated recently to account for the failure in building the documentation. Either way, I got it to build now!

2020-02-13 22:17:55 +0200	asked a question	Sage 9.0 fails to build Hi, My sage build for version 9.0 fails to build at the 'sagelib' step and it seems to be related to the GAP any pynac packages. I've attached the log for it so hopefully someone can help me figure out what's wrong with the build. Oddly enough, I have no problem building sage 8.8.
2020-02-06 17:46:57 +0200	asked a question	Sage notebook only runs when a browser is already open I just installed sage 8.8 (it's not the newest sage, but it works for the most part) on my Linux machine and I had everything working at some point but the other day it isn't working as I'd expect it to be. When I do `$ sage -n jupyter --browser=firefox` in the terminal without Firefox opened, I get ┌────────────────────────────────────────────────────────────────────┐ │ SageMath version 8.8, Release Date: 2019-06-26 │ │ Using Python 2.7.15. Type "help()" for help. │ └────────────────────────────────────────────────────────────────────┘ Please wait while the Sage Jupyter Notebook server starts...

[C 09:42:17.027 NotebookApp] To access the notebook, open this file in a browser: <server file> Or copy and paste one of these URLs: <localhost> (I don't have enough karma to actually post the links but "local host" is the link to the notebook and "server file" is the HTML file in "/var/run/user/.../nbserver-...-open.html") which seems fine but Firefox doesn't appear to be open. When I try to open another Firefox browser, I get a message saying that there is already another browser opened when there isn't and I would have to kill the Firefox processes in order to open it again. Interestingly, when I try the same command again with a browser already opened, a new tab with the sage notebook appears. I get the feeling that the problem could be coming from my init.sage file but I'm not sure if that would be the case. `~/.sage/init.sage: ================================== from sage.misc.viewer import viewer viewer.browser('open -a /usr/bin/firefox')` My environment variable SAGE_BROWSER is set to firefox: `$ echo $SAGE_BROWSER firefox` If there's anything else that you'd like me to provide, let me know.
