[Solved] Qt5.15 not found

Post by san15895 » Tue Aug 25, 2020 3:05 pm

Hello everyone.

I've installed FreeCAD recently and when I tried to use the "arch" workbench I got this error:

Workbench faiilure:
/lib/x86_64-linux-gnu/libQt5Core.so.5: version `Qt_5.15' not found (required by /usr/local/lib/python3.8/dist-packages/PyQt5/QtCore.abi3.so)

I googled my problem but came up with no solution that worked for me, so here I am. Hope you can help me.

Here is my install info:
OS: Ubuntu 20.04.1 LTS
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.18.4.
Build type: Release
Python version: 3.8.2
Qt version: 5.12.5
Coin version: 4.0.0
OCC version: 7.3.0
Locale: English/United States (en_US)

BR.
Santiago.

Please retry with a current 0.19.

How did you install it?

There may be a package from the Ubuntu universe repository, but usually this is not current. You may have better luck with the PPA, see Install on Linux, the AppImage, or the Ubuntu Snap.

I installed it with:
$ sudo apt-get install freecad

How can I uninstall and retry with another way?

I already uninstalled it and removed all the dependencies.

Where can I get the 0.19 version for Ubuntu?

Sorry for my ignorance. Just installed the Ubuntu Snap Developer Version (0.19).

It doesn't have the problem anymore, Thank you!

But is it normal for it to crash when I save a project?

Of course it's not normal. You may try the AppImage which minimizes dependencies on other things installed.

No.
I would strongly recommend for Ubuntu 20.04 to use the FreeCAD-daily PPA https://launchpad.net/~freecad-maintain ... ecad-daily
There is an upstream packing issue with QT5/Pyside(2)-tools, @kkremitzki works around this on the daily PPA. I don't think this work around has been implemented on the stable PPA yet.

And Welcome :)

Thanks everyone for your help (an welcoming).

I'll try this one now.
