From 26 Jul 2020 to 14 Aug I used to run Ubuntu 20.04. And have no issues with 'debsums -c' nor 'Path of Exile' self check. Then I reinstall debian completely (clean super duper install) using debootstrap and keep it running since. Two days later. On a day (today) 16 aug I ran booth debsums and POE PackCheck.exe and it failed:
Checking pack file Content.ggpk...

Fatal error: Your pack file has become corrupted. Currently the only way to fix this is to delete Content.ggpk and download it again by running the client.
Looks like Debian + my ssd has serious issues and not working properly together. I have no idea what to do next. Dmesg log attached. I also run logwatch on my debian distro and it did not report any issues.
