I was running into this as well, and I chose “DigitalOcean GrubLoader v0.2 (20160714) Debian” as my kernel (already had sudo apt-get install linux-image-$(uname -r) installed), ran poweroff , and turned instance back on via DO control panel. Now it’s working again!

Worked for me with the last kernel at the moment : Debian 7.0 x64 vmlinuz-3.2.0-4-amd64 (3.2.63-2+deb7u2)


i tried quite a few different kernels. i am a bit lost about this.

uname -a gives me : 3.2.0-4-amd64 #1 SMP Debian 3.2.54-2 x86_64 GNU/Linux

grub (even though it is ignored) seems to point (looking at the menu.lst and the date if the vmlinuz file) this kernel dates from mid january. Debian 7.0 x64 vmlinuz-3.2.0-4-amd64 (3.2.65-1+deb7u1)

i tried to select 3.2.54-2 kernel in droplet options, which by the way is only available in 32bit flavour. or 3.2.65-1+deb7u1. i also tried last debian update Debian 7.0 x64 vmlinuz-3.2.0-4-amd64 (3.2.60-1+deb7u3)

no luck with any of them.

did anyone got this sorted recently ?
