more careful packages handling, update shouldn't break container if was interrupted in the middle of packages installation

STR:

docker run -d -p 443:443 --name pmm-server percona/pmm-server:1.5.0
sleep 10
docker exec -it pmm-server pmm-update-check # run update check
curl -v -k -X POST https://127.0.0.1/configurator/v1/updates # run update via API call, web interface can be used also
sleep 5
docker restart pmm-server
sleep 2
docker ps

Expected result:
pmm-server container in running state, web interface is available, it is possible to rerun update 

Current result:
not possible to start pmm-server container, web interface not available, very hard to recover container from a broken state

Description:
It is needed to more careful install packages, update shouldn't broke container if it was interrupted in the middle of packages installation
real cause of interruption like network, OOM, docker restart is not important
