Hello César Bento Freire, I've wrote a small tutorial about installing Portuguese Citizen Smartcard Software, at https://blog.geomaster.pt/cartao-de-cidadao-no-ubuntu-18-04/
You can install manually libxerces-c3.1 as Evgeny Brazgin explained. It also depends on libcurl3. To install Evgeny Brazgin packages, please do: sudo add-apt-repository ppa:xapienz/curl34 sudo apt policy curl sudo apt remove curl libcurl4 sudo apt install curl=7.58.0-2ubuntu3ppa2 libcurl4=7.58.0-2ubuntu3ppa2 Evgeny Brazgin: thank you for providing the packages! Well done! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1754294 Title: After last updated libcurl3 on libcurl4, some apps are removed.
