there are borken packages and dependency issues in KDE Neon the configuration of my system is: lsb_release -a No LSB modules are available. Distributor ID: neon Description: KDE neon User Edition 5.7 Release: 16.04 Codename: xenial Reproducible: Always Steps to Reproduce: sudo aptitude install openscad The following NEW packages will be installed: libqt5scintilla2-12v5{a} libqt5scintilla2-l10n{a} openscad 0 packages upgraded, 3 newly installed, 0 to remove and 3 not upgraded. Need to get 3.064 kB of archives. After unpacking 11,5 MB will be used. The following packages have unmet dependencies: libqt5core5a : Breaks: libqt5scintilla2-12v5 (< 2.9.2+dfsg-2~) but 2.9.1+dfsg-4build1 is to be installed. The following actions will resolve these dependencies: Keep the following packages at their current version: 1) libqt5scintilla2-12v5 [Not Installed] 2) openscad [Not Installed] Accept this solution? [Y/n/q/?] Y Same thing, if I install the dependency directly: sudo apt install libqt5scintilla2-dev Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: libqt5scintilla2-dev : Depends: libqt5scintilla2-12v5 (< 2.9.1+dfsg+1~) but it is not going to be installed Depends: libqt5scintilla2-12v5 (>= 2.9.1+dfsg) but it is not going to be installed E: Unable to correct problems, you have held broken packages. I found a similar bug here: but it is a more general problem as more software is affected by this https://bugs.kde.org/show_bug.cgi?id=368319
needs archive rebuilder.. work in progress
I am also affected by this, cant install sqlitebrowser The following packages have unmet dependencies: sqlitebrowser : Depends: libqt5scintilla2-12v5 (>= 2.8.4) but it is not going to be installed E: Unable to correct problems, you have held broken packages.
Yes, bug is still not fixed in KDE neon 5.9
I am experiencing the same bug when trying to install Openscad on KDE Neon Dev Edition 5.9.2 Will this bug be confirmed and resolved?
The issue can be resolved by using the following procedure (taken from here https://github.com/openscad/openscad/issues/1792): thx GPHS, installing those two apckages first install https://www.ubuntuupdates.org/package/core/yakkety/universe/base/libqt5scintilla2-l10n then https://www.ubuntuupdates.org/package/core/yakkety/universe/base/libqt5scintilla2-12v5 using sudo dpkg -i <package-name> then sudo apt install openscad would it be possible to include these packages into kde neon?
Thank you Thomas, It worked perfectly for me! That is a great temporary fix but it would be great if Neon includes these. I guess it would be included if Neon upgraded to 17.04 ;)
Easy enough to confirm with sudo apt install libqscintilla2-qt5-dev an attempt to install libqscintilla2-qt5 itself results in a 'packages to remove' a large proportion of everything in KDE. I found this bug because this package is needed to compile octave-4.4 against Qt5. ./configure complains that 'something is broken with your Qt5 installation'. The instructions for compiling that under ubuntu are at https://www.scivision.co/compiling-octave-4-on-ubuntu/ The first step is to install the dependencies and this fails on libscintilla2-qt5-dev. This may be an ubuntu 16.04 package management issue but it in not good for a Qt5 package to have problems in KDE Neon. Maybe it is sorted out in ubuntu 18.04? .. but maybe not.
FWIW, the two packages mentioned above no longer exist. Is there any solution to this at this point? Has anyone gotten Octave to work on Plasma?
With current KDE Neon there is no problem installing libqt5scintilla2 or openscad. The problem seems relevant to very old Neon versions that are no longer supported.
