Estou enfrentando falhas de segmentação no Ubuntu 22.04 e queria pedir ajuda para depurar.

Eu tenho algumas corridas sudo apt-get update:Segmentation faultsts... 52%

Executando o atualizador de software, recebo:update-manager crashed with SIGSEV

Outro exemplo foi a remoção de um ambiente Conda.

Às vezes, executando scripts Python no Spyder:

/home/max/anaconda3/envs/spyder-env/lib/python3.11/site-packages/spyder/plugins/ipythonconsole/scripts/conda-activate.sh: line 18: 1216748 Segmentation fault      (core dumped) $CONDA_ENV_PYTHON -m spyder_kernels.console -f $SPYDER_KERNEL_SPEC


Fatal Python error: Segmentation fault

Restarting kernel...

Além disso, outros programas, como o Visual Studio ou o Google Chrome, travam sem erros.

Tentei:

  • Spyder reinstalado
  • Criei um novo ambiente conda reinstalando todos os pacotes que usei.
  • Corridoconda clean -a
  • Execute atualização e upgrade com apt-get
  • Executei o memtest, que passou sem erros
  • Teste de estresse da CPU
  • Tente corrigir pacotes quebrados no modo de recuperação, o que resultou em uma falha de segmentação.
  • Atualizar o BIOS
  • Atualize para o Ubuntu 24.04

Aqui está um trecho de um log (journalctl) que apareceu após uma falha de segmentação ao remover um ambiente conda:

Alguém tem sugestões sobre como encontrar a raiz desse problema? Eu poderia reinstalar o Ubuntu também, mas gostaria de entender o que está acontecendo.
