Dear all, I have a strange error with rabbitmq on ubuntu 20.04. The playbook was working previously on this OS but now I have this error: TASK [usegalaxy_eu.rabbitmq : install rabbitmq] **************************************************************************************************************************** task path: /home/galaxyluc/galaxy/roles/usegalaxy_eu.rabbitmq/tasks/Debian/install.yml:23 <galaxy.inbios.uliege.be> ESTABLISH LOCAL CONNECTION FOR USER: root <galaxy.inbios.uliege.be> EXEC /bin/sh -c 'echo ~root && sleep 0' <galaxy.inbios.uliege.be> EXEC /bin/sh -c '( umask 77 && mkdir -p "` echo /root/.ansible/tmp/ansible-tmp-1620999798.916904-12818219648644 `" && echo ansible-tmp-1620999798.916904-12818219648644="` echo /root/.ansible/tmp/ansible-tmp-1620999798.916904-12818219648644 `" ) && sleep 0' Using module file /usr/lib/python3/dist-packages/ansible/modules/packaging/os/apt.py <galaxy.inbios.uliege.be> PUT /root/.ansible/tmp/ansible-local-1239270zkwwo8m/tmpd5o4vaj2 TO /root/.ansible/tmp/ansible-tmp-1620999798.916904-12818219648644/AnsiballZ_apt.py <galaxy.inbios.uliege.be> EXEC /bin/sh -c 'chmod u+x /root/.ansible/tmp/ansible-tmp-1620999798.916904-12818219648644/ /root/.ansible/tmp/ansible-tmp-1620999798.916904-12818219648644/AnsiballZ_apt.py && sleep 0' <galaxy.inbios.uliege.be> EXEC /bin/sh -c '/usr/bin/python3 /root/.ansible/tmp/ansible-tmp-1620999798.916904-12818219648644/AnsiballZ_apt.py && sleep 0' <galaxy.inbios.uliege.be> EXEC /bin/sh -c 'rm -f -r /root/.ansible/tmp/ansible-tmp-1620999798.916904-12818219648644/ > /dev/null 2>&1 && sleep 0' fatal: [galaxy.inbios.uliege.be]: FAILED! => { "changed": false, "invocation": { "module_args": { "allow_unauthenticated": false, "autoclean": false, "autoremove": false, "cache_valid_time": 0, "deb": "/usr/src/rabbitmq-server-3.8.9-1.deb", "default_release": null, "dpkg_options": "force-confdef,force-confold", "force": false, "force_apt_get": false, "install_recommends": null, "only_upgrade": false, "package": null, "policy_rc_d": null, "purge": false, "state": "present", "update_cache": null, "upgrade": null } }, "msg": "Dependency is not satisfiable: erlang-crypto (< 1:24.0)|esl-erlang (< 1:24.0)\n" } Does anyone have any idea how to solve this ?
