Comment 1 Michail Vourlakos 2020-09-02 21:51:27 UTC

1. Are you sure that kde frameworks is 5.68? That codepath is executed only with 5.69 and above
2. Try to install kirigami2 library

1. yes, system info screenshot attached.
2. kirigami2 installed
$ dpkg -l | awk '/kirigami/{print $2 "_" $3}'
kirigami2-dev_5.68.0-0ubuntu2

https://invent.kde.org/plasma/latte-dock/-/commit/b2f8f204828f8cbcef629ba351d3ec57adfcfcdb

This commit seems to break functionality for me.

Anything before https://invent.kde.org/plasma/latte-dock/-/commit/89e94fce3b635c7017527dce4b5c68aed5fdd1c0 works fine.

Working Steps:
git clone https://github.com/KDE/latte-dock.git
cd latte-dock
git checkout 89e94fce
./install.sh
latte-dock --layout Default -d

Broken steps:
git clone https://github.com/KDE/latte-dock.git
cd latte-dock
git checkout b2f8f204
./install.sh
latte-dock --layout Default -d

Comment 6 Michail Vourlakos 2020-09-10 15:24:11 UTC

no idea how to fix this... this is a loader that becomes active only for KF5>=5.69 . If anyone can provide a valid fix, feel free to do so.
