As mentioned in the original bug report, this has been caused by Python3.10.
[ Test Plan ]
* Execute "linux-show-player"
* if its not fixed then it will fail as the error above
* With fixed package the "linux-show-player" window will be displayed.
[ Where problems could occur ]
This is an upstream patch which only changes the code to import the correct module and use integer-float properly. The only major change in the code is to call QRectF() instead of QRect() but QRectF() is basically same as QRect() with floating point precision. So, imho, there should not be any regression. Also, currently its completely unusable, there can not be a bigger regression than that.
[ Other Info ]
It has been fixed in upstream release 0.5.3 and so Mantic and Noble are not affected.
[ Original Bug Description ]
[Impact]
* It is currently not possible to run the repository-provided version (0.5.2) of `linux-show-player` upon Ubuntu 22.04. This is caused by Ubuntu 22.04 using python 3.10, which contains some changes that breaks `linux-
* Linux Mint 21 has relatively recently (2022-07-31) been released, which (re)uses the Ubuntu 22.04 repositories, and as such suffers from the same issue.
* Pop! OS 22.04 also (re)uses the Ubuntu 22.04 repositories, and as such suffers from the same issue.
* Upstream bug reports (and backtraces) can be found at:

* There exists a newer release of `linux-show-player` (0.5.3) which contains within it a fix for this issue (corrected imports and better differentiation of integer/float values).
* Users have reported that the newer release works for them, when they install it manually.
* The newer release is currently packaged and available in the repositories of the fledgling Ubuntu 22.10 release-to-be. (As well as the repositories of Debian 12 and Unstable.)
[Test Plan]
* Install package from repository;
* Attempt to run the program from the Launcher;
* Note that it does not start, or rather: it does but crashes;
* Attempt to run the program via a terminal [emulator]: `$ linux-show-player`;
* Note the errors (or lack thereof with the newer release);
[Where problems could occur]
* There are other changes contained in the gap between 0.5.2 and 0.5.3 beyond the fix for Python 3.10. That said, the other changes can be summarised as being mostly documentation and CI improvements, along with a branding update and a new translation. A full changeset may be found here: https:/
* The changes required to get `linux-show-player` to work on python 3.10 are compatible with earlier versions of python 3.x, so there shouldn't be a problem if a user prefers to use an earlier version of python. (The project doesn't support python 2.x, and as such is not expected to run under that.)
[Other info]
* Note that I myself do not use Ubuntu or a Ubuntu-derived distro: I am a contributor to the linux-show-player project who is filing this on behalf of our users who use Ubuntu 22.04 and Linux Mint 21. I am hoping that this is a simple case of backporting the package from 22.10 to 22.04, but lack the resources to test this.
