Dear Maintainer,

when doing a normal 'apt upgrade' on Sid, I find that element-desktop
(currently at 1.11.110) can't be upgraded (for the moment, to 1.12.0),
see the following output:

    Preparing to unpack .../element-desktop_1.12.0_amd64.deb ...
    Unpacking element-desktop (1.12.0) over (1.11.110) ...
    dpkg: error processing archive /var/cache/apt/archives/element-desktop_1.12.0_amd64.deb (--unpack):
     error creating hard link './usr/share/icons/hicolor/512x512/apps/element-desktop.png': Invalid cross-device link
    update-alternatives is /usr/bin/update-alternatives

A fact about my system that I imagine can be a cause for this issue is
that my /usr is a different device than my / :

    $ df
    Filesystem              1K-blocks       Used Available Use% Mounted on
    ...
    /dev/nvme0n1p2           10218772    6139092   3539008  64% /
    /dev/mapper/system-usr  472292536   17571644 430656280   4% /usr

Cheers,
Richard
