Ubuntu 20.04: “EXT4-fs (sdb2): VFS: Can’t find ext4 file system”-error

do flag

I am quite new to Linux and have recently started to use Ubuntu. At first it worked, but for the last three days, every time I started my computer I get in emergency mode and this error message appears: “EXT4-fs (sdb2): VFS: Can’t find ext4 file system”. I tried to follow the instructions from other users that had the same problem, but it somehow doesn’t work for me.

For anyone to be able to help you will have to provide some more information. Boot the system from the Ubuntu install disk/usb and choose try Ubuntu. Copy and paste the output of `lsblk’ into your question. Mount your root partition and copy and paste the contents of /etc/fstab from that partition into your question. Also, if you understood what you were doing, please describe as best you can what you have already tried.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
