I have 15.04 installed and I get this error (not blocking, everything works but seeing this is annoying) while updating:

update-initramfs: Generating /boot/initrd.img-3.19.0-16-generic
ln: failed to create symbolic link ‘/root/lib/systemd/system/cdrom.mount’: No such file or directory

I digged some and found out that I get this when I try to update initramfs:

$ sudo update-initramfs -u

Searched online but couldn't find anything related. I don't have a cdrom/dvdrom on my machine by the way.

  • Are you booting from a USB thumb drive? – Antony Jun 16 '15 at 19:55
  • No but I installed from USB thumb drive and my PC doesn't have a CD/DVD rom. – Gokhan Sari Jun 18 '15 at 11:46
  • Well, in my case, I boot and use Ubuntu off a USB drive, and whenever I do sudo apt-get dist-upgrade, and if it updates packages like linux kernels, I would see errors as such. That is even with the computer having a CDRom Drive – Antony Jun 18 '15 at 13:32

It would seem that there is a bug in whatever package update-initramfs is running the update for, where it is trying to generate the cdrom.mount symbolic link at the wrong path, /root/lib/systemd/system/, rather than at /lib/systemd/system/.

Which package is causing this? We need more information.

I have discovered that if you manually create that empty folder structure under /root before running anything, it will then create a cdrom.mount symbolic link there during the update. I would assume that one might even think to manually copy that symbolic link over to /lib/systemd/system/. I tried that, but I don't know if doing it actually fixes any problems.
