Ubuntu22.04安装GStreamer出现版本不符问题求助

现象 #

我在Ubuntu 22.04系统中执行以下命令安装GStreamer：

sudo apt-get install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libgstreamer-plugins-bad1.0-dev gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio

但执行gst-launch-1.0 --version显示版本为1.14.0：

gst-launch-1.0 --version
gst-launch-1.0 version 1.14.0
GStreamer 1.14.0
Unknown package origin

通过apt-show-versions和重新安装命令确认，系统已安装的libgstreamer1.0-dev是预期的1.20.3-0ubuntu1版本：

apt-show-versions libgstreamer1.0-dev
libgstreamer1.0-dev:amd64/jammy-updates 1.20.3-0ubuntu1 uptodate


sudo apt-get install libgstreamer1.0-dev

libgstreamer1.0-dev is already the newest version (1.20.3-0ubuntu1).
0 upgraded, 0 newly installed, 0 to remove and 8 not upgraded.

这是我第三次在该电脑上全新安装Ubuntu并尝试部署GStreamer，此前相同步骤可成功安装1.20版本，其他电脑曾出现1.14/1.16版本的情况。我想了解出现版本不符的原因，以及如何获取1.20版本。

推测原因 #

我推测问题源于先安装了Anaconda3，其自带旧版本GStreamer，导致系统优先调用Anaconda版本而非apt安装的版本，目前除卸载Anaconda外不知其他解决办法。
