I was attempting to install MidiEditor. I got my file from the official downloads page (https://www.midieditor.org/index.php?category=download) but on both terminal and Ubuntu Software but they say the following error: https://i.stack.imgur.com/cfzhA.png The following packages have unmet dependencies. midieditor : Depends: qt5-default but it is not installable Depends: gstreamer1.0-doc but it is not installable E: Unable to correct problems, you have held broken packages. I tried installing qt5-default, but it gave me a "E: Package 'qt5-default' has no installation candidate" error. Can anyone fix this?

Edit: Running MidiEditor gives nothing, running midieditor gives the following error:
/usr/lib/midieditor/MidiEditor: error while loading shared libraries: libQt5Multimedia.so.5: cannot open shared object file: No such file or directory

  • Which version of Ubuntu are you using? – Archisman Panigrahi May 15 '22 at 08:29
  • 22.04 "Jammy Jellyfish" – thes_real May 15 '22 at 08:43
  • You can create a fake `qt5-default` package. https://askubuntu.com/a/1181415/124466 Let us know if there is any further issue. – Archisman Panigrahi May 15 '22 at 09:29
  • I created the packages, but running `sudo apt .install /midi*.deb --fix-broken` gets me further except qt5-default is still halting the installation. – thes_real May 15 '22 at 13:15
  • Did you install the fake qt5-default package first? – Archisman Panigrahi May 16 '22 at 01:36
  • I did, but now entering `midieditor` in the prompt gives the following error: /usr/lib/midieditor/MidiEditor: error while loading shared libraries: libQt5Multimedia.so.5: cannot open shared object file: No such file or directory – thes_real May 16 '22 at 15:55
  • Try `sudo apt install libqt5multimedia5` – Archisman Panigrahi May 16 '22 at 16:58
  • @Archisman Panigraphi, It was saying for me to enter in `sudo apt --fix-broken install` and I did, but then I had to reinstall MidiEditor due to it randomly removing itself, and after plenty of typing commands (the command was `sudo apt install ~/qtbase5-dev*.deb ~/qt5-default*.deb /home/thes_real/Downloads/midieditor_3.3.0-1-amd64.deb` after building lots of packages) I got it to work, thank you! – thes_real May 17 '22 at 15:35
