Bug ID: 480465
Summary: Currently released Qt5 distribution has libqt5script5
package at level 5.15.11, which is not at the same
level as the rest/core Qt5 at 5.15.12
Classification: KDE Neon
Product: neon
Version: unspecified
Platform: Neon
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Packages User Edition
Assignee: neon-b...@kde.org
Reporter: flederm...@comcast.net
CC: j...@jriddell.org, neon-b...@kde.org, sit...@kde.org
Target Milestone: ---
When attempting to start mythtv (V33a) backend (mythbackend), it immediately
exits.
My machine:
Linux tvacq 6.2.0-39-generic #40~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Nov 16
10:53:04 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
Actual error:
tvacq mythbackend: mythbackend[2891]: I CoreContext
mythcommandlineparser.cpp:2922 (operator()) Qt: Cannot mix incompatible Qt
library (5.15.11) with this library (5.15.12)
It is clear that libqt5script5 is one minor revision too old. I suspect that it
was not included in the latest wave of Qt updates.
Here is a list of the Qt libraries in /lib/x86_64-linux-gnu/ and their version
called by mythbackend:

This worked until the Qt5 update released the week of that came out the week of
1/22/24
STEPS TO REPRODUCE
1. Ubuntu Neon 22.04 system with mythtv V33a installed and updated as of
1/27/24
2. start mythbackend in shell by hand
3. observe output in shell or check /var/log/mythbackend
OBSERVED RESULT
Immediate exit of mythbackend due to incompatible libraries
EXPECTED RESULT
Ongoing running of mythbackend

ADDITIONAL INFORMATION
Adding a 5.15.12 scripts library of the right version but wrong libc level
changed the error message, confirming that it was the library causing a
problem.
