I have faced with this error with two programs on a newly installed Ubuntu 18.04.
I get the following error message when I run "lifeograph" after instaling it using Software Center or Synaptic.
lifeograph: error while loading shared libraries: libatkmm-1.6.so.1: cannot open shared object file: No such file or directory
I get the same error "while loading shared libraries" with another program, "keepassxc":
keepassxc: error while loading shared libraries: libQt5Network.so.5: cannot open shared object file: No such file or directory
I tried to run the following command but it did not help:
sudo /sbin/ldconfig -v
Ubuntu 18.04 is a LTS release. Above mentioned programs are from official repositories. Getting such errors on a a freshly installed LTS system is surprising.
Do you have any suggestions?
