So today it's Recoll, it says it's installed but it won't launch. When I try through the terminal it says

error while loading shared libraries: libQt5Widgets.so.5: cannot open shared object file: No such file or directory

So I tried

sudo apt-get install libqt5-widgets

and get 

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package libqt5-widgets

I haven't been able to install any new programs since I got 18.04 a month ago, some of them install and even launch but they never work, there is always something missing. I always get a message about some missing dependency.

I have all the repository boxes ticked in the settings.

I've tried apt-get update and apt-get upgrade

I've looked at threads with similar topics and no answer. 

apt-cache policy recoll
recoll:
  Installed: 1.23.7-1
  Candidate: 1.23.7-1
  Version table:
 *** 1.23.7-1 500
        500 http://ftp.heanet.ie/pub/ubuntu bionic/universe amd64 Packages
        100 /var/lib/dpkg/status


$ which recoll
/usr/bin/recoll

This happens no matter what program I try to install.

Thanks.

According to the search on packages.ubuntu.com you need to get libqt5widgets5 package with

sudo apt-get install libqt5widgets5

Also for your information Recoll is available in official repositories (in universe pocket) too and installable with

sudo add-apt-repository universe
sudo apt-get install recoll

To be completely sure that your system integrity is complete consider to use debsums.

  • Yes I got it from the official repositories, I get everything from there, but no matter what I get from the official repositories there are missing dependencies. So yeah, "'universe' distribution component is already enabled for all sources. " – Rabbit Jan 06 '19 at 20:47
  • When i did that it said "libqt5widgets5 is already the newest version", and I still get the same error message when i try to open recoll. I don't understand what the link you sent me wants me to do? – Rabbit Jan 06 '19 at 20:49
  • Ah ha ok i figured out what the debsums stuff was about, sorry it took me a while. Yes, that worked, sorted out all the missing dependencies and all the programs I've been trying to install are working now. Thank you! – Rabbit Jan 15 '19 at 17:12
