Very old deprecation messages during installation, and a failure

[alxx]

Apparently large parts of the Electron app have been based on deprecated libraries, and now installation doesn't seem to be working at all anymore:

/fret/fret-electron$ npm run fret-install

> fret@3.0 fret-install
> npm run clean ; npm install && npm --prefix ../tools/LTLSIM/ltlsim-core install ../tools/LTLSIM/ltlsim-core && npm run build


> fret@3.0 clean
> rm -rf app/node_modules ; rm -rf ../tools/LTLSIM/ltlsim-core/node_modules ; rm -rf ../tools/LTLSIM/ltlsim-electron/node_modules ; rm -rf node_modules

npm WARN deprecated core-js@2.6.12: core-js@<3.23.3 is no longer maintained and not recommended for usage due to the number of issues.

Hi @alxx ,

Thanks for reporting this. Could you please let us know more details about the machine you are trying to install FRET, as well as the versions of the dependencies that you have installed? So far, I've been unable to replicate this on Ubuntu using Node version 16.16.0 and 18.19.1 (the one that appears in the log file that you shared).

Best,

Andreas

Hello, thanks for being so quick!

$ uname -a
Linux censored 6.8.0-106-generic #106-Ubuntu SMP PREEMPT_DYNAMIC Fri Mar  6 07:58:08 UTC 2026 x86_64 x86_64 x86_64 GNU/Linux

I'm attaching the entire installation log, hope the answer are there.

Hi @alxx ,

Thank you for your response. I still am unable to reproduce this issue on my end. The error message suggests a network connectivity issue during the installation, which may be due to specific network settings in the machine that you are using.

As an alternative I would recommend trying to build a Linux executable on a different machine where you don't encounter network connectivity errors like the one in your log file. Then, you can transfer the binary to the machine with the stricter network settings. FRET does not require a network connection during its operation, so you shouldn't face any issues while using the tool.

Best,

Andreas
