There appears to be a bug in all appimage versions since 5.1.4. It is also projecting forward in all the nightly builds. The bug does not occur however in the current Flatpak 5.2.2 version from PyQt5.QtTest import QTest QTest.qWait(2000) print('I was waiting for two seconds') returns the following: ImportError: /lib/x86_64-linux-gnu/libQt5Test.so.5: undefined symbol: _Z32qt_register_signal_spy_callbacksRK21QSignalSpyCallbackSet, version Qt_5 ------------- System: Kernel: 5.4.0-167-generic x86_64 bits: 64 compiler: gcc v: 9.4.0 Desktop: Cinnamon 5.2.7 wm: muffin 5.2.1 dm: LightDM 1.30.0 Distro: Linux Mint 20.3 Una base: Ubuntu 20.04 focal Machine: Type: Desktop Mobo: ASUSTeK model: PRIME A320M-K v: Rev X.0x serial: <filter> UEFI: American Megatrends v: 5603 date: 10/14/2020 Memory: RAM: total: 15.62 GiB used: 3.27 GiB (21.0%) RAM Report: permissions: Unable to run dmidecode.

My old login details point to a defunct email address which I no longer have access to.
I cannot reproduce this, I'm afraid. Running the script in krita's scripter or running it in a system python both work for me.
I have encountered this as well on linux mint If I try the script my error is a bit different: ********************** ImportError: libQt5Test.so.5: cannot open shared object file: No such file or directory In file: <string> In function: <module> at line: 1. Line with error: ********************** on my pc it seems even appimages before 5.1.4 have the same problem. I have tried the latest nightly, the stable from the Krita website, appimage 5.1.4 and 5.1.3, 5.1.2 and it happens in all of those.
I've tried again, with 5.1.5 I could reproduce something like this: ********************** ImportError: /tmp/.mount_krita-Ayc0zk/usr/bin/../lib/libQt5Core.so.5: version `Qt_5.15' not found (required by /lib/x86_64-linux-gnu/libQt5Test.so.5) In file: <string> In function: <module> at line: 1. Line with error: ********************** But no longer with 5.2.3, so I am closing this bug as fixed, since the way we add Python to the appimage has been changed.
