Out of memory error while calculating md5sums for md5sum.txt

Alexandre,

Would you please run Cubic from the command-line, and share the output?
Just open a terminal, type "cubic" and press enter.
When you get to the point where you encounter this issue, please cut and paste the output from the terminal here?

So I can try to recreate this issue:
- What is the output of "lsb_release --all" on your host machine.
- Which ISO are you trying to customize?

Hi!

My LSB_RELEASE --ALL

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04 LTS
Release: 18.04
Codename: bionic
____________________________________________
The ISO: Ubuntu Mate 18.04 AMD64

And the LOG from command line is

  Update md5 sums

OK. Thanks. I'll look at this.

Alexandre,

Would you please test the fix for this bug in the *Development* branch, and let me know if it resolves your problem?

    # Remove Cubic
    $ sudo apt autoremove --purge cubic

    # Remove the *Release* repository
    $ sudo apt-add-repository --remove ppa:cubic-wizard/release

    # Add the *Development* repository
    $ sudo add-apt-repository ppa:cubic-wizard/development

    # Install the *Development* version of Cubic
    $ sudo apt update
    $ sudo apt install cubic

it works ;)

Good work and tank you

You're welcome, and thanks for testing.

I'll promote this to the release version, this evening, so others can get this fix as well.
(Remember to revert to ppa:cubic-wizard/release!)
