Trouble encountered after updating to v2.3.2

Question

After updating to the latest v2.3.2, some trouble arises. Here are some error messages

Answer 1

What happens with cadabra2 (the command-line client)? On which system is this, and I assume you installed from source?

Comments

Can you see the picture?

Yes, I installed from source, the system is Ubuntu 18.04 in WLS. The error message is as follows

  ~$ cadabra2-gtk 
    terminate called after throwing an instance of 'std: truntime_error"
    too short
    At:
    cadabra2_defaults.py(12): \langlemodule> <string>(2) ;< module>
    terminate called after throwing an instance of 'std: : logic_error what (): Failed to read port fron server. 
    Aborted (core dumped)

---

Tell me what 'cadabra2' spits out; I need to know if this is a problem with the python module or with the cadabra server.

---

I cannot open 'cadabra2' standalone. When I input cadabra2 in the command line, and the error messages as following:

Traceback (most recent call last):
  File "/usr/local/bin/cadabra2", line 29, in <module>
    from cadabra2 import *
ImportError: /usr/local/lib/python3.6/site-packages/cadabra2.so: file too short

---

If you cannot start cadabra2 at all ('command not found') then you have other problems which you need to sort out first.

---

The command cadabra2 can be found, but It doesn't work. The error messages have been updated above.

---

That suggests that /usr/local/lib/python3.6/site-packages/cadabra2.so is corrupt; it's about 30M on my machine. Did something go wrong during sudo make install?

---

I have deleted the file 'cadabra2', and reinstalled from the source. After this, the command cadabra2' work fine in the command line, but when I input something like 'ex:=1+1;` in standalone, the following errors arise:

Generic typesetting error; LaTeX failed. Please report a bug.

I don't know what's wrong.

Your LaTeX installation does not have the etoolbox package installed.

---

The package etoolbox has been installed, but Cadabra couldn't seem to find it. It's so strange, after all, in the previous version, everything is perfect,

---

If you do

cd /tmp
pdflatex fileadLFBc.tex

from the terminal, does that complain about the same etoolbox?

(that filename was taken from the error message above).

---

The error massage is

! LaTeX Error: File `ytableau.sty' not found.

Type X to quit or <RETURN> to proceed,
or enter new name. (Default extension: sty)

---

So you need the ytableau package (that's a new requirement for 2.3.2).

Ok, problem solved, thanks.
