After adding this PPA for Ubuntu Xenial (16.04) to install qt5.11: https://launchpad.net/~beineri/+archive/ubuntu/opt-qt-5.11.0-xenial and updating with
apt-get, I encountered this issue while trying to install the package "qt511-meta-full" (the package "qt511-meta-minimal" shown no issues):
$ sudo apt-get install qt511-meta-full Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: qt511-meta-full : Depends: qt511doc:any but it is not installable E: Unable to correct problems, you have held broken packages.
And of course, I can't find the package "qt511doc" itself:
$ sudo apt-get install qt511doc Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package qt511doc
Any help or fix is appreciated. Thanks.
