Unable to reproduce, it is possible to get a sample file that contains this issue? |

I found the line in the journal, but I can't share. The issue was caused by a line created by ansible, where the uid is set to the word "None". Dissect tries to parse this to an Integer. The check in "/usr/local/lib/python3.9/dist-packages/dissect/target/plugins/os/unix/log/journal.py" line 261 checks if the variable is None, but not if the contained string is 'None'. An easy fix would be to check if the value is the string None. Tried this and it worked: |

Hello there!
I get this error quite often when I try to get information about linux images (e.g. ip adresses):
Traceback (most recent call last):

ValueError: invalid literal for int() with base 10: 'None'
Is there a way to fix this?
