Comment 25 for bug 1873008

Hi, The issue happened to me with zfs on root + neon grub theme.

Failing on the unable to make backup link of './boot/grub/themes/breeze/progress_bar2_c.png' before installing new version: Operation not permitted
dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)
Errors were encountered while processing:
 /var/cache/apt/archives/grub-theme-breeze_5.19.5-0xneon+20.04+focal+build9_amd64.deb

Any idea on possible solution/workaround?
