--- Comment #9 from catandras48+...@gmail.com --- Hello David! Thank you also for your support. When I try to install the package okular-dbgsym: andreas@t490:~$ sudo apt install okular-dbgsym [sudo] password for andreas: 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: okular-dbgsym : Depends: okular (= 4:19.12.3-2ubuntu1) but 4:20.04.0-0ubuntu1~ubuntu20.04~ppa3 is to be installed E: Unable to correct problems, you have held broken packages. Okular crashes immediatly after opening the file. "uncommon screen arrangement": Yes, I'm pretty sure you found the cause of the problem: I use a the Lenovo UltraDockingStation and two FHD displays attached. One is horizontally 1920x1080 and the other is pivoted vertically 1080x1920. When I detach the notebook, Okular opens successfully. When I switch off the vertical display, Okular also opens without crashing. Well ... that's it. But how can I or we solve it? -- You are receiving this mail because: You are the assignee for the bug.
