I have an installed ubuntu 23.04 on a flashdrive partition type ext2. I’m migrating everything to another ubuntu installation on an ext4 filesystem on another device. On both systems I have userid stuart 1000 group 1000. Booting from the new installation, I cannot read any files owned by me on the ext2 device, though permissions may be 777. If I try to do any kind of operation on those files, I get “permission denied” or “input/output error”. Even “ls -l” gives “input/output error (though it displays the proper result”). Stunningly, I cannot read those files with sudo, either! If I boot to the ext2 device, those files are readable just fine. I am a sudoer on both systems. Partition Manager shows the ext2 partition correctly on the ext4 installation; “mount” shows it mounted as ext2 ro. What’s the problem here? -Stuart
Followup:I believe the problem was transitory and electrical: I shutdown the system, removed the errant device and moved it to another port -viola! Files are readable as normal. I’ve migrated off the device, so the problem needn’t recur. Thanks for your time. -Stuart
ls -l, as well as the exact error (the wording is important).
