Public bug reported: In a host where ceph-mds is installed, upgrading from 14.2.11-0ubuntu0.19.10.1~cloud4 to 15.2.8-0ubuntu0.20.04.1~cloud0 fails with:
dpkg: error processing archive /tmp/apt-dpkg-install-Zen6uw/9-ceph-common_15.2.8-0ubuntu0.20.04.1~cloud0_amd64.deb (--unpack): trying to overwrite '/usr/bin/cephfs-data-scan', which is also in package ceph-mds 14.2.11-0ubuntu0.19.10.1~cloud4 dpkg-deb: error: paste subprocess was killed by signal (Broken pipe) Errors were encountered while processing: /tmp/apt-dpkg-install-Zen6uw/9-ceph-common_15.2.8-0ubuntu0.20.04.1~cloud0_amd64.deb E: Sub-process /usr/bin/dpkg returned an error code (1) The problem happens because /usr/bin/cephfs-data-scan is provided by ceph-mds in 14.2.11-0ubuntu0.19.10.1~cloud4: # dpkg -S /usr/bin/cephfs-data-scan ceph-mds: /usr/bin/cephfs-data-scan However in 15.2.8-0ubuntu0.20.04.1~cloud0 it is provided by ceph-common: # dpkg -S /usr/bin/cephfs-data-scan ceph-common: /usr/bin/cephfs-data-scan A quick workaround is to temporarily remove ceph-mds before the upgrade (dpkg -r ceph-mds) and then perform the upgrade process using apt install. It will upgrade all packages and reinstall ceph-mds. ** Affects: ceph (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/1919261 Title: Upgrading Ceph from 14.2.11-0ubuntu0.19.10.1~cloud4 to 15.2.8-0ubuntu0.20.04.1~cloud0 fails when ceph-mds is installed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ceph/+bug/1919261/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
