Title:
update-initramfs fails with an error 'Error 24 : Write error : cannot
write compressed block'
Status in initramfs-tools package in Ubuntu:
Confirmed
Bug description:
On a VirtualBox 6.1.14 VM with 2 vCPUs and 8 GB RAM and a 10 GiB hard
disk space, I installed Ubuntu 20.10 with ZFS enabled on a full disk
installation using the latest installer ISO available on the Ubuntu
releases site.
After installation, I booted into the installed OS and tried to
install all the package updates. It went mostly fine till when it
tried to run the update-initramfs operation and failed. Below are the
relevant messages printed to the console.
