error: no server is specified. error: no suitable video mode found. /dev/sdc2: clean, 259918/15630336 files.
After this error screen for few seconds it automatically boots into Ubuntu.
Need Help :)
Avoid *buntu.
For me the question is rather, what’s the current raison d’être for Ubuntu if you’re not looking for Debian with paid support?
Granted it’s been long since I’ve used it (I used it from 2005 or so until 2008 when I switched to Arch), but there’s no really appealing quality for me there that I couldn’t have with Debian. Apart from that, Canonical makes questionable decisions – snap, as others have mentioned, a total disaster in my opinion; Mir was another of their misadventures (later retrofitted into a Wayland compositor); upstart didn’t turn out successful (though to give credit, it was an honest attempt at a new init system and lessons were learned); the LXD maintainer issue as of late leaves a sore taste in my mouth, plus they were always very community-unfriendly with their CLAs. And all this for what? Might as well use their upstream instead.
According to DDG it’s a Grub issue. There are a couple of things you could try by searching that error message.
As it boots fine (and changing into wayland later) I think you can just ignore it.

It’s not exactly a bug. It’s just that Linux is extremely verbose and often spits out debug messages for things that are not relevant to your system.
No, it is a bug (I think) because GRUB should display in native resolution and because of a bug can’t figure it out and displays in 800x600. It is however only cosmetic.
I had this error several times (also cases where it would not boot afterwards). It usually appears after installing Nvidia drivers.
