Programs installed in Snap format do not detect the keyboard

I deleted the Superproductivity installation and the files from the Snap folder. I installed from the software center. It still doesn't work.

I don't think this is related to CLI vs GUI but I did notice this today on my Focal system. I think it's a bug in the input stack. I will chase after this with assistance from the desktop team next week.

I confirm that the installation form has nothing to do with it. In Spotify only the username is supported but not the password

This bug affects all snap applications.

This looks to be due to snaps being denied connection to the ibus socket:

[ 791.681769] audit: type=1400 audit(1581897497.906:247): apparmor="DENIED" operation="connect" profile="snap.firefox.firefox" pid=27136 comm="pool" family="unix" sock_type="stream" protocol=0 requested_mask="send receive connect" denied_mask="send connect" addr=none peer_addr="@/home/amurray/.cache/ibus/dbus-Rb6gdmxA" peer="unconfined"

So ibus was recently updated in focal and this moves the ibus socket path from /tmp to the users home directory - the existing desktop_legacy interface species the ibus socket path in /tmp still:

# allow communicating with ibus-daemon (this allows sniffing key events)
unix (connect, receive, send)
    type=stream
    peer=(addr="@/tmp/ibus/dbus-*"),

So this needs to have something like the following added:

unix (connect, receive, send)
     type=stream
     peer=(addr="@/home/*/.cache/ibus/dbus-*"),

to the desktop-legacy interface (OR ibus is reverted to move the socket back to /tmp however from a security point-of-view I think it is better to have the ibus socket address in the user's home directory).

I don't think there is a way to use the @{HOME} variable in this rule hence the /home/*/ above

I've submitted a PR to snapd to add this new path https://github.com/snapcore/snapd/pull/8141

Ah and now I see Jamie has already submitted a better PR - https://github.com/snapcore/snapd/pull/8139 - so please track that instead :)

This was merged and released directly to Focal. The next release of snapd will include this fix in general.

Note that if you are on focal, you may still not get this fix if you have the edge channel of the core/snapd snaps installed, as snapd will re-exec into that channel, and the edge channel currently is lagging behind the debian package of snapd. We expect the edge channel to be properly rebuilt soon, but in the meantime you can switch channels for the core/snapd snap to stable and you will get the fix from the debian package in focal.

Started just having this issue yesterday for chromium and discord installed as a snap after running an update (on focal)

Reporting it as it's almost 2 months since the last comment not sure if maybe something got reverted on last update.

The last ibus update is 4 days old, and it should be unrelated, so this is probably a different issue.
Can you check the output of "journalctl -f | grep DEN" while running those snaps, and attach it here?

I was able to fix this by changing the input method settings.

When first opening it, I see a window saying:

Current configuration for the input method:
 * Active configuration: default (normally missing)
 * Normal automatic choice: ibus (normally ibus or fcitx or uim)
 * Override rule:
 * Current override choice: (en_US)
 * Current automatic choice: ibus
 * Number of valid choices: 2 (normally 1)
The override rule is defined in /etc/default/im-config.
The configuration set by im-config is activated by re-starting X.
Explicit selection is not required to enable the automatic configuration if the active one is default/auto/cjkv/missing.
  Available input methods: ibus xim
Unless you really need them all, please make sure to install only one input method tool.

I hit Okay.
Then another window pops up saying:
Do you explicitly select the user configuration?
Select No, if you do not wish to update it(recommended)
select yes, if you wish to update it.

I select "yes"

On the new window I see that "default" is select. (use auto mode set /etc/default/im-config)

I went to that file and cat it, the result below:
# Default im-config mode (see im-config(8))

OLDIFS="$IFS"
IFS=':'
desktop=
for val in $XDG_CURRENT_DESKTOP; do
    for d in 'GNOME' 'MATE' 'UKUI' 'Unity'; do
        [ "$d" = "$val" ] && { desktop="$d"; break 2; }
    done
done
IFS="$OLDIFS"

if [ -n "$desktop" ]; then
    # Start best input method unless overridden below
    IM_CONFIG_DEFAULT_MODE=auto
else
    # Start best input method only if CJKV environment and not overridden below
    IM_CONFIG_DEFAULT_MODE=cjkv
fi

# Set locale dependent preferred IM over standard auto mode
if [ "$desktop" != 'GNOME' ]; then
    IM_CONFIG_PREFERRED_RULE="zh_CN,fcitx:zh_TW,fcitx:zh_HK,fcitx:zh_SG,fcitx:ja_JP,fcitx:ko_KR,fcitx:vi_VN,fcitx"
fi

# User and system wide configuration is normally done via im-config program.
# The above IM_CONFIG_PREFERRED_RULE sets locale dependent preferred IM
# override rule. If you wish to use uim over ibus just for ja_JP,
# add :ja_JP,uim at the end of the above list.

# Trace commands for debug
# (This may cause problem configuration file generated under console mode)
#IM_CONFIG_SETMODE="-x"

# Verbose output for debug (uncomment following)
#IM_CONFIG_VERBOSE="true"

-------------

If i change the input method to "auto" (activate IM with @-mark for most locales) the keyboard works again on all snaps

I hope the information I provided helps somehow

sorry i forgot to also mention that i have chinese and japanese ibus. For some reason now my icon on the top right is gone too

Hi. I'm getting a similar issue but it's related with the context menu from the tray icon. I'm the maintainer of prospect-mail but I also see this issue in https://super-productivity.com/ snap app.

Julian, I suspect your snap needs to 'plugs: [ unity7 ]' (which is what allows using dbusmenu) and that you need to 'snap connect prospect-mail:unity7'. If the interface is already connected, please fil a new bug and include the policy denials from journalctl corresponding to when the functionality wasn't working.

This issue was fixed in snapd 2.43 which was since released to the stable channel. Marking as such.

On closer look it seems that the patch was included in 2.44.

I'm on snap 2.47 and chromium does not respond to the keyboard. It is version:
Version 86.0.4240.75 (Official Build) snap (64-bit)

System info:
Ubuntu 20.04.1 LTS (64-bit)
GNOME 3.36.3 with Wayland

Why am I on Wayland...? Not sure! I thought I stuck with X... Maybe that's part of the problem.

Let me know if there are any other specs that would help.

In addition, I have noted many corrupt icons since switching to the snap package. For example, the close button in the upper right that should display as a simple X has some weird shaped whale looking icon attached to the left side of it. When I go to save a file, the system icons I have selected are not display, instead corrupted icons or no icons display. I'm not sure if this is related to the keyboard issue, but they both occurred after upgrading to snap.

Chris, could you please attach the output of the following command:

    snap connections chromium

For the issue with corrupt icons, please file a separate bug at https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+filebug. Thanks!

If installed through Snap and with iBus running the keyboard doesn't work in Standard Notes, XMind and Chromium apps on Manjaro 21.1. Killing iBus fixes the issue.
The keyboard works in Visual Studio, however

Marat, this specific issue was fixed a while ago, so the problem you're experiencing is most likely a different one.

Would you mind filing a new bug at https://bugs.launchpad.net/snapd/+filebug ?
