please see https://github.com/giampaolo/psutil/issues/1251
(this is in the official repository of psutil, and if you want to work
on this, please coordinate there)
Sage merely uses psutil as a Python module, and, I repeat, it is not
crucial one for Sage.

Re: [sage-support] SageMath 8.7 crashed in WSL Ubuntu after installation
Dear my devolopers,
I have tried the installation on the other PC, which is a windows 10
virtual machine on my MacBook Pro.
The warning message is the same as the other PC, which said the Python
pcutil module cannot detect the status of my hardwares.
I am trying to fix this problem.
Thanks. Regards

Re: [sage-support] SageMath 8.7 crashed in WSL Ubuntu after installation
Dear my friend,
I do the installation under your help. I reinstalled the sagemath software
with the steps:
1. download the latest version of SageMath 8.7 for Linux Ubuntu 18.04, and *mv
sage-8.7-Ubuntu_18.04-x86_64.tar.bz2 /usr/local/*
2. Reinstall WSL Ubuntu 18.04
3. *mkdir /usr/local/SageMath && chown -R newton /usr/local/SageMath*
4. *cd /usr/local/ tar xjvf sage-8.7-Ubuntu_18.04-x86_64.tar.bz2*
*5. chown -R newton /usr/local/SageMath*
*6. cd SageMath/ && ./sage*
*7. chown -R newton /usr/local/SageMath*
*8. alias sage='/usr/local/SageMath/sage'*
when I type sage in terminal with normal user*,* sage can be used. But
there is still a warning:
newton@Newton-PC-4:~$ sage
┌┐
│ SageMath version 8.7, Release Date: 2019-03-23 │
│ Using Python 2.7.15. Type "help()" for help. │
└┘
/usr/local/SageMath/local/lib/python2.7/site-packages/psutil/_pslinux.py:469:
RuntimeWarning: 'sin' and 'sout' swap memory stats couldn't be determined
and were set to 0 ([Errno 2] No such file or directory: '/proc/vmstat')
warnings.warn(msg, RuntimeWarning)
*sage*: 1 + 1
2
*sage*:
Is it the bug of WSL or there is still something wrong?

Re: [sage-support] SageMath 8.7 crashed in WSL Ubuntu after installation
I guess he uses sudo to install the sagemath deb package as he is using
the nativ (!) one... But sorry for insisting, the last version of sage
on the web site is much more recent and can be used in home .

I am sorry for showing that. But now, I can use sagemath with this command in

I think this is because I use sagemath the first time with sudo. I don't know
what happened during I running sagemath the first time.
This is because Sage maintains a data cache in ~/.sage/
Running Sage with sudo created/updated files in ~/.sage/ with wrong
(i.e. root) ownership,
It might have also changed ownerships of some files in
~/SageMath/local/ - although this is less likely.
You can see ownerships in ~/.sage/ by running "ls -alR ~/.sage/", and
similarly for ~/SageMath/
You can (actually, you should) change ownerships back to your "normal" user
bu running "sudo chown -R ~/.sage/ "
and "sudo chown -R ~/Sage/ "
(where should be replaced by your real username, -
something that on "real" Linux systems
is printed by the command "whoami")
This is assuming that "chown" actually works on WSL as it should...
Then it should not be necessary to use "sudo" any more.
Using "sudo" is a bad idea in such a case, e.g. as in Python you have
full access to the file system, so you can accidentally destroy your
WSL installation.
Let us know if all this makes sense and works.
Q2
and does it still work if you don't use the alias?
alias just replace the command. There is no different between alias the the
original command.
Q3
Anyhow, we need a detailed bug report if you like us to look at it
("it crashed" is not enough - we need to see error messages, relevant
log files, etc)
I am sorry for my issue not so detailed. I use sagemath to do the experiment in
my bachelor thesis. This PC for doing experiment still in the lab. I will come
back to run the installation again and get the log file.
Thanks.

This appears to be completely unnecessary.
When I first finished the installation, the first running is very normal. However when
the second time I add "alias sage='~/SageMath/sage'" and type sage in terminal,
it crashed.

This is because Sage maintains a data cache in ~/.sage/
Running Sage with sudo created/updated files in ~/.sage/ with wrong
(i.e. root) ownership,
It might have also changed ownerships of some files in
~/SageMath/local/ - although this is less likely.
You can see ownerships in ~/.sage/ by running "ls -alR ~/.sage/", and
similarly for ~/SageMath/
You can (actually, you should) change ownerships back to your "normal" user
bu running "sudo chown -R ~/.sage/ "
and "sudo chown -R ~/Sage/ "
(where should be replaced by your real username, -
something that on "real" Linux systems
is printed by the command "whoami")
This is assuming that "chown" actually works on WSL as it should...
Then it should not be necessary to use "sudo" any more.
Using "sudo" is a bad idea in such a case, e.g. as in Python you have
full access to the file system, so you can accidentally destroy your
WSL installation.
Let us know if all this makes sense and works.

Re: [sage-support] SageMath 8.7 crashed in WSL Ubuntu after installation
Q1
> why did you use sudo ?
This appears to be completely unnecessary.
I am sorry for showing that. But now, I can use sagemath with this command
in *.bashrc*
*alias sage=''sudo ~/SageMath/sage'*
I think this is *because* I use sagemath the first time with *sudo*.* I
don't know what happened during I running sagemath the first time.*
Q2

*alias* just replace the command. There is no different between alias the
the original command.

I am sorry for my issue not so detailed. I use sagemath to do the
experiment in my bachelor thesis. This PC for doing experiment still in the
lab. I will come back to run the installation again and get the log file.
Thanks.

and does it still work if you don't use the alias?
Anyhow, we need a detailed bug report if you like us to look at it

[sage-support] SageMath 8.7 crashed in WSL Ubuntu after installation
Dear my friends,
After I installed the sagemath 8.7 in Windows Subsystem for Linux Ubuntu
18.04, crash happend.
*(decomperssed ==> move folder to my home directory ==> sudo ./sage).*
When I first finished the installation, the first running is very normal.
However when the second time I add "alias sage='~/SageMath/sage'" and type
sage in terminal, it crashed.
what happened here? Is WSL not so stable or the bugs in Sage 8.7 made the
crash?
