I got the same error. I used the gz files to install Texstudio 2.12.6 and added the PPA in order to upgrade to .10.
Getting this eerror in the installation: dpkg: error processing archive /tmp/apt-dpkg-install-cr8gIt/8-texstudio_2.12.10-0~201807041908~ubuntu18.04.1_amd64.deb (--unpack): trying to overwrite '/usr/share/texstudio/tabletemplate_fullyframed_firstBold.js', which is also in package texstudio-doc 2.12.6+debian-2 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773164 Title: package texstudio (not installed) failed to install/upgrade: trying to overwrite '/usr/share/texstudio/tabletemplate_fullyframed_firstBold.js', which is also in package texstudio-doc 2.12.6+debian-2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/texstudio/+bug/1773164/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
