This is a duplicate of: fsck e2fsck: Cannot continue, aborting
because I can not comment there and it is obvious to me that people marking this as duplicate and the one's responding didn't really read/understand what the problem is.
On a fresh install of XUbuntu 18.04.2 if I used the "Extended Options for Ubuntu" and use any "...(revovery mode)" entry and in the following menu I choose "fsck check all filesystems" I initially got:
/lib/recocery-mode/recovery-menu: line 80: /etc/default/rcS: No such file or directory
fsck from util-linux 2.31.1
/dev/sda4 is mounted
e2fsck: Cannot continue, aborting.
As there was no /etc/default/rcS on the installed Xubuntu 18.04.2 system and none on the Xubuntu live DVD, I checked an old 16.10 live DVD and that had a /etc/default/rcS, that bassically consisted of a bunch of options that were commented out. so I copied it over. and when I now try "... (recovery mode)" "fsck..." I get:
fsck from util-linux 2.31.1
/dev/sda4 is mounted
e2fsck: Cannot continue, aborting.
Being a newbee I spent the last 2 days to try to find out how I can fix this permanently (I did file a bug-report). I need to get on the road with this laptop and when being on the road I need this "fsck..." menu to work as I can not run around with a big pile of paper of all the things I need to remember about bypassing problems in the boot process. I won't have access to the internet if that laptop fails. I did not want to try to copy the /lib/recocery-mode/ folder from the old 16.10 live DVD to 18.04.2 as I'm worried I might create damage that way and I just can not spend another 2 days searching with no useable result. I don't want to take the risk of booting an unchecked filesystem that might be corrupted (etc. because of power failure) either.
