[Bug 1874312] Re: error: cannot open `/boot/efi/EFI/ubuntu/grubx64.efi': Read-only file system.

[Sebastien Bacher]

the log has

Apr 22 19:38:13 ubuntu ubiquity: Installing for x86_64-efi platform.
Apr 22 19:38:23 ubuntu kernel: [  703.524619] FAT-fs (sda2): error, fat_free_clusters: deleting FAT entry beyond EOF
Apr 22 19:38:23 ubuntu kernel: [  703.524623] FAT-fs (sda2): Filesystem has been set read-only

looks like the filesystem was corrupted

** Summary changed:

- Something wrong
+ error: cannot open `/boot/efi/EFI/ubuntu/grubx64.efi': Read-only file system.
