[Workaraound] Python-IDE ERIC fails to install (python3-pyqt5.qsci should not be installed)

Post by gogo555 »

Hi all,

problem is discussed too at: http://www.linuxmintusers.de/index.php?topic=39477.0

Mint-18-KDE 64bit
(uname -a : Linux pc051 4.4.0-53-generic #74-Ubuntu SMP Fri Dec 2 15:59:10 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux)

~3 weeks ago my fully working eric 6.0.8 was automatically DEinstalled during an "apt update".

Now it's not re-installable again.
Errormessage:
... eric : depends on: python3-pyqt5.qsci (but should not be installed)

console-outputs are in German only (as I use a german Linux-Mint-KDE). To provide you with English outputs, I wanted to install Sarah on virtualbox but the installer doesn't work (defect "continue"-button on page 3) --- fixed that - the virtual System had not enough space, a bigger virtual drive did it (a hint during from the installer would have been fine ...)
so ... outputs are in English:

and so on ...

A try with "aptitude install eric" gave no solutions.

Anything that I can do?

Code: Select all

pc051 ~ $ aptitude why-not eric
Unable to find a reason to remove eric.
pc051 ~ $ aptitude why-not python3-pyqt5.qsci
Unable to find a reason to remove python3-pyqt5.qsci.
pc051 ~ $ aptitude why-not libqt5scintilla2-12v5
i   libqt5core5a Breaks libqt5scintilla2-12v5 (< 2.9.2+dfsg-2~)
pc051 ~ $ aptitude why libqt5core5a
i   plasma-integration Depends libqt5core5a (>= 5.6.0~beta)
I think this is the tree of dependencies that makes the problem - I filed a bug

There's a workaround:
https://bugs.launchpad.net/linuxmint/+b ... comments/5

Installing version 2.9.3 of libqt5scintilla2-12v5 and libqt5scintilla2-l10n (download and install manually from https://www.ubuntuupdates.org/package/c ... illa2-l10n and https://www.ubuntuupdates.org/package/c ... illa2-12v5 ) resolves the package-conflicts.
