Public bug reported: 1) Description: Ubuntu 20.04.3 LTS Release: 20.04
2) python3-opencv: Installed: (none) Candidate: 4.2.0+dfsg-5 Version table: 4.2.0+dfsg-5 500 500 http://us.archive.ubuntu.com/ubuntu focal/universe amd64 Packages 3) I expected 'apt install python3-opencv` to complete without issue. 4) Issuing: 'apt install python3-opencv` fails with: "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: python3-opencv : Depends: libopencv-dnn4.2 (= 4.2.0+dfsg-5+20.04.sav2) but it is not going to be installed Depends: libopencv-superres4.2 (= 4.2.0+dfsg-5+20.04.sav2) but it is not going to be installed Depends: libopencv-contrib4.2 (>= 4.2.0+dfsg) but it is not going to be installed E: Unable to correct problems, you have held broken packages." Drilling down, 'libopencv-dnn4.2' requires 'libprotobuf23' which is not available for 20.04, but is available for 20.10. ** Affects: opencv (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1951867 Title: python3-opencv fails to install due to unmet dependency.
