You were right, this was entirely my bad sorry - I should have tried to build locally before commenting. This was an issue with chaotic-aur's build process.

@jthvai Thanks for the report! That's odd, python-pip-system-certs is explicitly listed as a dependency and should prevent this error. Are you sure that package did install correctly on your machine?

This is my output on pacman -Ql python-pip-system-certs

Otherwise maybe force an install via paru -S python-pip-system-certs --asdeps but I don't want to recommend this way for everyone if your problem is reproducible. I was not able to reproduce it on three machines of mine though. Let me know if you have further information about particularities of your setup.

Following the update to 24.04, anki now fails to launch with

Traceback (most recent call last):
  File "/usr/bin/anki", line 5, in <module>
    from aqt import run

I can confirm what @patenteng described. I tried to compile it too again with version 23.12.1-3 but the rustc process was killed again at arount 6 GiB. This time I did not use the TTY.

Works fine now.

@AlexBocken I recompiled, but I don't think it made much difference. It peaked at 8.3 GiB + 2 GiB for the rest of the OS with KDE only having closed all other applications. In my comment below I meant it used 10+ GiB in total.

@Spixmaster thanks for the detailed triage! The problem is most likely the new method for LTO which uses fat LTO objects, requiring more RAM. From personal testing with clang, gcc and mold (the old way) I could not find a large difference in RAM usage personally. All were around ~2.5 GiB at the worst moments. So what you're experiencing might be specific to some machines.

Nonetheless I've returned to the old way of doing LTO using mold in -3 as that appears to be more reliable across machines.

I've switched in -2 to using Fat LTO objects since that is the recommended way to fix this issue (see arch gitlab link in comments in PKGBUILD). For people who prefer their linker of choice, this method is still available by manually uncommenting the corresponding lines. The default is now again mold to allow for maximum compatibility.

@patenteng @AlexBocken I further investigated the issue. For that, I used the TTY to minimise RAM usage.

From the fact that I was able to compile it the last time I considered what I changed since then which was that I set up sccache. I disabled it then this second time. It did not change the outcome noticably. My laptop has 7.64 GiB of RAM. The rustc process was killed at around 6.7 GiB of memory usage both times. According to @patenteng, it takes more than 10 GiB. I do not know what happened since last time I compiled because then I was able to do so. Maybe a change from QT5 to QT6.

Nevertheless, I will go with anki-bin.

RAM use when compiling is very high. It went to 10+ GB on my system.

@AlexBocken I monitored the RAM usage particularly know. You seem to be right and I hope that that is the reason. Thank you very much!
