Public bug reported: Ubuntu release: 20.04.3 LTS
apt-cache policy libopencv-dev output: libopencv-dev: Installed: (none) Candidate: 4.2.0+dfsg-5 Version table: 4.2.0+dfsg-5 500 500 http://archive.ubuntu.com/ubuntu focal/universe amd64 Packages I attempted to "apt-get install libopencv-dev:arm64" from an amd64 system (it's a docker image, but I don't think that should affect anything) for the purposes of cross-compiling. The error I get is: #13 471.4 Some packages could not be installed. This may mean that you have #13 471.4 requested an impossible situation or if you are using the unstable #13 471.4 distribution that some required packages have not yet been created #13 471.4 or been moved out of Incoming. #13 471.4 The following information may help to resolve the situation: #13 471.4 #13 471.4 The following packages have unmet dependencies: #13 471.5 libopencv-dev:arm64 : Depends: libopencv4.2-java:arm64 (= 4.2.0+dfsg-5) but it is not installable #13 471.5 Recommends: opencv-data:arm64 but it is not installable #13 471.5 E: Unable to correct problems, you have held broken packages. I believe this is because libopencv4.2-java is not an arch-specific package (architecture is listed as "all"), and the "arm64" specification is throwing things off. Note the same issue for opencv-data, but that's just a "recommends", and so is not actually breaking anything for me. As a band-aid, I going the "equivs" route to build a empty libopencv4.2-java:arm64 and libopencv4.2-java:armhf packages to technically satisfy the dependency since I'm not actually using those packages, but that's oh-so-hacky. Is there a better work-around until this gets fixed? ** 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/1949279 Title: libopencv-dev doesn't install when specifying arm64 from an amd64 system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/opencv/+bug/1949279/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
