I have tried two things: (1) Fresh install, Ubuntu 18.04 (about ten days ago), ext4. No errors during the installation. However, when installing stuff via apt afterwards (or upgrading), I got many errors along the lines described above (e.g., "compressed data is corrupt... unexpected end of file or stream"). This happened for, I guess, arbitrary packages. No errors for initramfs update for me ...
(2) Fresh install, Ubuntu 18.04 (about four days ago), btrfs for /. No errors at all. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1746340 Title: Samsung SSD corruption (fsck needed) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1746340/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
