qemu-system-s390x. Could not read keymap file: 'en-us'

qemu (Ubuntu)

Bug Description


 * Debian has split some common files like icons, keymaps, base man&doc
   pages (e.g. of interfaces), trace event defintion into an extra package
   called "qemu-system-data". The ubuntu-only package qemu-system-s390x
   needs to follow that split.

 * The impact of missing that isn't huge, you'll miss key maps or not find
   docs, but it is easy to resolve and feels wrong to have the default
    experience (e.g. calling it with no arguments) to report an error.

 * Fix is "just" adding the right dependency to the qemu-system-s390x

[Test Case]

 * on s390x, install qemu-system-s390x
 * Before the fix this would not pull qemu-system-data, for testing make
   sure this isn't by accident installed by another dependency or you
   won't be able to reproduce this issue.
 * run it
    $ qemu-system-s390x
    Could not read keymap file: 'en-us'

[Regression Potential]

 * The change is to the s390x package only and only an extra dependency.
   So if anything it will consume slightly more disk space by pulling
   things in, but since those were formerly part of qemu-common which is
   pulled in still that is fine.

[Other Info]

 * Mostly this issue was hidden for various reasons
   - dependencies often pull in qemu-system which pulls qemu-system-
     <arch*> and the others pull qemu-system-data correctly.
   - Furthermore unless you need non en-us input, inist on the icon or
     need the api doc you'll run in no issues - for example all the tests
     we ran on cosmic were happy

When installing qemu-kvm and running without -nographic
I get the following error:
# qemu-system-s390x -enable-kvm
Could not read keymap file: 'en-us'

When I use -nographic everything is fine.

So it seems that the qemu-kvm package has some missing dependencies (or misses some files).

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode.

To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/1798084/+editstatus and add the package name in the text box next to the word Package.

This commit can give a clue:


- d/control-in: qemu-keymaps is provided by qemu-system-data now (from yet
unreleased Debian version)

Perhaps system is missing this qemu-system-data package that delivers /usr/share/qemu/keymaps/en-us file.

in qemu 2.12 that was split in Debian and the only-Ubuntu qemu-system-s390x package misses that following the split.

Thanks for the report Christian.

This isn't severe but should be fixed.

Due to Cosmic being in the last steps to be released I doubt the Release Team will make the update soon.
But I'll prepare it as it would be an SRU then they can decide to
a) get it into cosmic-release
b) accept it as day-0 SRU

Thereby I hope to avoid having to wait the opening for 19.04 to fix that.

status: New → Triaged

Fix is pushed and tagged in Git.
Test PPA is building in https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/3489

Once build I'll ran a test and a few other verifications and then push it for the Release Team to decide on accepting now or as 0-day SRU.

Multi-repo confusion, refreshed PPA and git :-)

Working fine as expected from the PPA.

Uploaded to Cosmic, but as outlined before we have to check when/where it lands due to the release being finalized at the moment.
