[Bug 2017182] Re: package initramfs-tools 0.136ubuntu6.7 failed to install/upgrade: installed initramfs-tools package post-installation script subprocess returned error exit status 1

[Mikkel Kirkgaard Nielsen]

The issue I experienced here, with ~0 bytes free on /boot, produces a
more clear "no space left" error than other initramfs-tools post-
installation bugs.

See Df.txt;
/dev/sda1                      238924    232193         0 100% /boot

See end of DpkgTerminalLog.txt;
