Hi, While multiple versions of openjdk-*-jdk could be installed at the same time, it is not the case for packages that provide debugging symbols for post-11:
--8<---------------cut here---------------start------------->8--- $ for v in 8 11 12 13 ; do p="openjdk-$v-dbg" ; echo $p ; apt-cache show $p | grep Conflicts ; done openjdk-8-dbg openjdk-11-dbg openjdk-12-dbg Conflicts: openjdk-11-dbg openjdk-13-dbg Conflicts: openjdk-11-dbg --8<---------------cut here---------------end--------------->8--- So, debug symbols for JDK 11, 12 and 13 are not co-installable. -- Mykola Libre/Free Java Software Developer https://manandbytes.gitlab.io/
