Issue
I updated package libwebkit2gtk-4.0 yesterday (2022-10-05) with command apt update, and it turns out to be a disaster. It breaks the application I develop that uses WebKitGTK as its back-end. Also, the new version libwebkit2gtk-4.0 outputs tons of run-time warning, so I consider it a buggy version. How can I get the old version back? Thanks.
My /etc/mx-version is
MX-19.4_ahs_x64 patito feo March 31, 2021
and /etc/debian_version is
10.13
Solution
In debian you can use the following path to downgrade:
apt policy MX
this will show you all the versions available in the repos and
apt install MX=<exact.version.package>
will install that specific version. You may also need to downgrade some dependencies in order to make it work.
