Ubuntu Boot Issues

Ubuntu's default partitioning makes the boot partition really small. I usually go in and make it bigger when I install Ubuntu.

Here is what Ubuntu did on my UniFi controller. It has a 127GB vhdx because I was lazy and just clicked next through the VM creation wizard.

In the week or so since we discussed "Why CentOS and not Ubuntu" there are like 3 of these annoying types of things every day.

Hyper-V default VHDX size in the New VM screens.

So I just tried to upgrade my UniFi controller since I noticed it was stuck on 16.04. Apparently when it upgraded from whatever previous version it was on, the release flag got set to only upgrade to the LTS line /sigh...

/etc/update-manager/release-upgrades was set to Prompt=lts

I changed it to Prompt=normal and then did the upgrade. Boom not enough space on /boot.

@JaredBusch When I upgraded to 16.10, it also disabled the unifi repos and I had to go in and enable them again.

That is normal with ever distribution upgrade in unbuntu. i know and expect that. part of the upgrade process is to disable all 3rd party repos.

@JaredBusch Good to know... this was the first time I upgraded a distro and didn't realize that would happen.

This right here is hateful.

New release available run this.

Run that, and no release found ugh - but linux is so much the easy.

Read that,.//

Did that,

JaredBusch

I never bothered to check syntax, google told me to do this.

bnaadmin@bnauc02:~$ sudo do-release-upgrade -d

It worked.

I'm not out to learn Ubuntu practices.

yea,.. just did that too..

Still showing no release found.

Honestly, you spent too much time on this. I would have performed a backup and installed a new system then migrated.

You only have to install to the same version to make it all work.

I mean that screen shows it is Ubuntu 14.04 FFS

Really thinking that also. Tired of being jerked around on something so ' simple and easy'. When it works it is...

Currently 4.x - I don't recall right off, and don't directly feel like signing into it. New VM created, just need to get an ISO mounted to start the install. But as it's not critical - Monday task.....

All this means is that you need to install the UniFi 4.x on the new system first, not the 5.x branch.
Then once you see everything reporting in, you can change to the UniFi 5 line.
