I tried to upgrade from SageMath 9.5 to 9.6 without success. because the code below generate error with 9.5:TypeError: unable to find a common ring for all elements

def _(v=('vector', input_grid(1, 3, default=[[1,2,3]], to_value=lambda x: vector(flatten(x))))):


WSL2,W11,Ubuntu 20.04

I wanted to keep the old version 9.5 which is in the sage directory,so I renamed sage to sage-9.5 and then rename the sage-9.6 directory to sage. the compilation time was much lower than usual, moreover the make does not signal an error. I had thought that maybe it was because I was using make -j32 ,so the compilation takes 30 minutes which is suspicious but I got the same PB with make alone which take 111 min only !.

real    111m46.476s
user    114m7.313s
sys     5m34.121s
Sage build/upgrade complete!
make[1]: Leaving directory '/home/ortollj/sage-9.6'

there are some messages in configure process

config.status: creating convenience symlink venv -> local/var/lib/sage/venv-python3.8

    notice: the following SPKGs did not find equivalent system packages:

          4ti2 coxeter3 gp2c igraph libsemigroups lrslib pari_elldata pari_galpol pari_nftables pari_seadata polymake _recommended

checking for the package system in use... debian

    hint: installing the following system packages, if not
    already present, may provide additional optional features:

      $ sudo apt-get update
      $ sudo apt-get install  4ti2 pari-gp2c libigraph-dev lrslib polymake libpolymake-dev default-jdk libavdevice-dev


    hint: After installation, re-run configure using:

      $ ./config.status --recheck && ./config.status

but when i run the recommended commands I got :0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

I forgot to tell the message I got:

ortollj@DESKTOP-K30FLRP:~$ cd sage
ortollj@DESKTOP-K30FLRP:~/sage$ sage
It seems that you are attempting to run Sage from an unpacked source
tarball, but you have not compiled it yet (or maybe the build has not
finished). You should run `make` in the Sage root directory first.
If you did not intend to build Sage from source, you should download
a binary tarball instead. Read README.txt for more information.

The code with interact still generate the same error in SageMath 9.6 in my computer than in 9.5 but this code in SageCell don't produce any error , why ?

when I type version() on sagecell I got:

'SageMath version 9.6, Release Date: 2022-05-15' same as mine.

@slelievre : do I have to open a new issue for this ?

Renaming the directory where Sage is installed is not supported.

Instead, use symlinks.

For example, install Sage 9.5 and Sage 9.6 in ${HOME}/sage-9.5 and ${HOME}/sage-9.6, and run:

$ sudo ln -sf ${HOME}/sage-9.5/sage /usr/local/bin/sage95
$ sudo ln -sf ${HOME}/sage-9.6/sage /usr/local/bin/sage96
$ sudo ln -sf ${HOME}/sage-9.6/sage /usr/local/bin/sage

Then run sage or sage96 to run Sage 9.6, and run sage95 to run Sage 9.5.

Ok @slelievre I will try,

But it still seems to me that the duration of the MAKE command (30 min only) is suspect, right?

Ooops, maybe that already having a complete sage directory makes the compiler believe to have already done part of the job?

@slelievre :I just did the make -j32 , but I'm skeptical, the duration of the make seems way too short

[sagemath_doc_html-none] Build finished. The built documents can be found in /home/sage-9.6/local/share/doc/sage/html/en/thematic_tutorials

in addition to slelievre cmd:

sudo ln -sf ${HOME}/sage-9.6/sage /usr/local/bin/sage

I also had to modify at the end of .bashrc:

nano ~/.bashrc

alias sage=/home/sage-9.6/sage

nano ~/

cd '/mnt/c/Documents and Settings/user/Mes documents/IPYNBpc'
/home/sage-9.6/sage --notebook jupyter

and now I just have to click on my SageMath W11 shortcut and all is ok
