No worries. Glad I could help.
The final issue that you saw is useful information, and I'm not sure how Mojang will deal with it when they get around to trying to fix this. Obviously openjdk-11-jre semantically conflicts with minecraft-launcher. The old way of dealing with this might have been to add a Conflicts: openjdk-11-jre to the deb control file. This is now necessary since many users will have unfortunately installed Java 11 because of the incorrect Depends: default-jre declaration; these all need to be fixed (at least for people who want to run older versions of Minecraft), but there is no automatic way to do this, and a Conflicts: declaration is pretty heavy handed (though the alternative of a Breaks: field is not possible since it has to be made in the breaker, not the breakee).
The only suggestion that I can make here is that the package should detect the presence of openjdk-11-jre during pre-inst and emit a warning to the user with instructions to remove that package. Maybe they should talk to a debian packager to understand how to get themselves out of the mess they have created.
Mojang, lyssnar ni inte?
It's working for me with 1.15. Maybe Mojang will migrate to Java11 at some point, but they haven't yet.
Looks like it's still picking up openjdk-11's java then. Run sudo apt purge openjdk-11-*.
Can you try sudo apt remove minecraft-launcher and then do sudo dpkg -i Minecraft~jzfixed.deb again.
Also, before you do that (just for my information), can you paste the output of dpkg -s minecraft-launcher.
The following will do the whole thing, including the download (first line) and install (last line - if it complains at the end, do sudo apt-get install -f).
wget https://launcher.mojang.com/download/Minecraft.deb
mkdir tmp
cd tmp
ar p ../Minecraft.deb control.tar.gz | tar -xz
sed -i 's/default-jre/oracle-java8-installer | openjdk-8-jre/' control # This edits the control file.
cp ../Minecraft.deb ../Minecraft~jzfixed.deb
tar czf control.tar.gz *[!z]
ar r ../Minecraft~jzfixed.deb control.tar.gz
cd ..
rm -rf tmp
sudo dpkg -i Minecraft~jzfixed.deb
Use the file name for the launcher that you have. I rename mine so that they match the version they are since Mojang for some unfathomable reason gives every version the same file name, "Minecraft.deb". So you can repeat the instructions above with file-roller Minecraft.deb and so on. You'll need to do that in the directory where the file is.
Never apologise for lack of knowledge. I'll explain what I mean, if it's at too much detail please excuse that.
Yes, "deb" means a dot-deb file. The dependencies are a list of packages that a package needs in order to work correctly. In this case, the Minecraft launcher package needs to have a Java installation in order to work (among other things), previously the version of Java that was specified was Java 8. Recently, the package maintainer changed the java dependency to the default Java version for ubuntu (this makes sense except that the default Java version on ubuntu is now Java 11 - which does not work with a whole swathe of things, including any Minecraft version prior to 1.13).
(Instruction note: all monospaced text in the instructions below are things tho type into the terminal).
OK, so much for the theoretical details. The dependencies are specified in the deb file (which as the stack exchange answer says is actually an archive in ar format). You can see this by opening the deb with file-roller (in a terminal try running file-roller Minecraft-2.1.9618.deb - or whichever version you have there); you'll see three files in the archive: "debian-binary", "data.tar.xz" and "control.tar.gz", the last being the one we want to change, but can't unfortunately with file-roller, though if you double click on it, you'll see its contents which look like the following:

In our case we want to change the text that says "default-jre" in the "Depends:" line to say "oracle-java8-installer | openjdk-8-jre". So after editing it will look like this:
Package: minecraft-launcher
Version: 2.1.9618

Copyright: All rights reservedAfter that's the case you continue the instruction from stack exchange. The instructions say that you should change the "Version:" line to something like (in your case) "Version: 2.1.9618~jz1", but in practice in this case that won't be necessary.
After you've finished all that and put the changes back into the deb file with ar r ../Minecraft-2.1.9618~jz1.deb control.tar.gz you can then do sudo dpkg -i ../Minecraft-2.1.9618~jz1.deb. This will re-install the launcher without marking Java 11 as a dependency.
Now, if dpkg complained that it can't install the launcher because of unsatisfied dependencies (this is unlikely if you had the launcher installed with a version prior to this bug), then you can do sudo apt-get install -f, which will install all the things that it needs to satisfy the deps.
At this point I would also then do sudo apt-get --purge autoremove, which will remove any packages that were automatically installed as dependencies but are no longer required. This will remove Java 11, which may cause other java-dependent programs from working because java dependency management is a nightmare.
I hope this helps. Please feel free to response here if you get stuck.
Also, to Mojang, the amount of work that it would require for you to fix this is vastly less than the amount of work that I've just put into helping one of your paying users. I think you should be feeling some form of shame for this.
Yes, you will need java 8 installed, but that will likely already be there since it was needed until this was broken. If it's not, just do sudo apt install -f to fixup the installation after you do the dpkg install.
You can edit the control file in the deb. You need to change the dependency from "default-jre" to the previously used deps, "oracle-java8-installer | openjdk-8-jre".
In the absence of adequate support provided here, you can follow the instructions here. I used the ar approach (after "Rather than mess with permissions...") since it's simpler.
This is a one-line change to fix. Is there any reason it's taken more than 6 weeks without movement?
Done
This has been made valid again by virtue of enforcing a java 11 dependency on the minecraft-launcher package. This deb now is dependent on default-jre, which is in turn dependent on openjdk-11-jre. This means that you've enforced a broken launcher, and unfortunately push java 11 system wide which breaks many other things.
beta 2.1.9080 fixes the 100% cpu burn issue, though the ld.so fault still exists.
A further additional problem is that the beta brings a dependency on java 11, which has issue running some versions of the game. For example, attempting to run 1.12.2 from beta-2.1.7658 results in the following crash
Inconsistency detected by ld.so: dl-lookup.c: 111: check_match: Assertion `version->filename == NULL || ! _dl_name_match_p (version->filename, map)' failed!
Process crashed with exit code 127This is apparently a known OpenJDK java 11 issue.
In addition to that minor problem, it continues running after launching minecraft and burns 100% cpu while it's doing it.
Seems to work, though now getting Launcher update notification. Maybe a ordered inequality should be used for version comparison; 2.1.7658 (the beta's version) > 2.1.5965, yet that is what it points to.
Instructions for debian are still incorrect. apt-get does not handle direct install of deb files.
@jcoy0907 Yes. That is what I wrote.
Still broken (2.1.5965). It is possible to select with the mouse, but only if the click is over the version that is being requested. This looks like the click is being dropped through to underlying listeners.
This is not a duplicate of 11234. The underlying cause may be the same, but the behaviour here is entirely different. Until one or both is fixed, or a clear indication of the underlying issue is clearly stated, both issue should be open.
This is still broken on the recently released 2.1.10835 version. This means that an upgrade from a manually fixed version as described above will break the user again. Thanks.
Note the
default-jrein the Depends line here.
