Hi,
Ubuntu Pro worked perfectly for me on Ubuntu 24.04.
After moving to Ubuntu 26.04, I now get a message saying that Ubuntu Pro is not available for this release.
I am using the same machine and the same valid Ubuntu Pro account, so I am wondering if Ubuntu 26.04 is not yet officially supported, or if this is a bug.
Has anyone else seen this issue.
Thanks.
Moved to Support and Help
What does pro status return?
By Ubuntu Pro, I mean the extended security updates and long-term maintenance benefits that come with a personal Ubuntu Pro subscription.
As far as I know, each personal account includes up to 5 machines, and I was using it without any issue on Ubuntu 24.
So this is not about activation in general â it worked correctly before. My confusion is that on Ubuntu 26 it now reports that this release is not eligible / supported.
That is why I am trying to understand whether Ubuntu 26 has not yet been added to Ubuntu Pro support, or if something has changed in policy / compatibility.
I have never used pro (with only 2 machines never really saw the need for it).
Hopefully someone else can answer but I suspect it is just too early right now immediately after release.
Sorry I am not able to offer a more definitive answer at this time.
I think itâs just a Segurity Center Snap issue; it canât quite detect whether youâre on Resolute yet. It should be fixed soon. In the meantime, you should be able to activate Ubuntu Pro using the old âSoftware & Updatesâ tool or via the terminal. Iâm not at my PC, so I canât confirm.
On my Resolute I have Ubuntu Pro:
corrado@corrado-n4-resolute:~$ inxi -Sc

Iâll share a screenshot later this evening when I get home.
On my system, Ubuntu Pro is currently inactive because it says this release cannot use Ubuntu Pro / is not supported for this version.
Just did a fresh install of 26.04 in a VM and it says the same thing in Security Center.
I guess we need to waitâŠ
It is a BUG of security center, I installed UbuntuPro from terminal giving my token:
corrado@corrado-n3-jammy:~$ sudo pro attach ... my token ...
I just submitted a bug: Security center says i don't have UbuntuPro - snap - snapcraft.io
Good to know, thanks for confirming.
As an aside, the number of machines should not inform that decision. If you want security support for packages in the Universe repository you want Ubuntu Pro:
Ever since Ubuntuâs initial release the lack of security support for Universe had been my personal number one on the list of its cons.
Plus, there is kernel live-patching, so one doesnât need to reboot right away. But thatâs more of a bonus in case of desktops, rather than a vital component.
But that only concerns the auto-connect to the system-observe plug:
sudo snap connect desktop-security-center:system-observe
This rights the ship manually.
Canât find the bug, but the issues is base-files didnât get updated properly, so /etc/os-release is missing LTS from the VERSION string. This will get fixed soon.
in the meantime, yes, connecting via the CLI is a workaround
This one is the linked in @corradoventuâs bug report:
and it gave me the idea.
Does that mean, that 26.04 systems will still be falsely flagged as ineligible for Ubuntu Pro, despite above workaround? I have tested on 24.04 with the desktop-security-center snap, so that might explain why it works for me. I cannot test with 26.04, though. @corradoventu, can you?
But it looks like the next stage of the workaround could be a simple:
osr=/etc/os-release
if ! grep -Fq 'VERSION="26.04 LTS' "$osr"; then
sudo sed -ri.bak 's/(^(VERSION="26.04)/\1 LTS/' "$osr"
fi
unset osr
(just had a peek at the base-files package and only the VERSION needs changing)
The above is a very condensed way of saying â and doingâ, make a backup copy of /etc/os-release and edit the line in the original file that starts with âVERSION=â and insert a space character and âLTSâ so it looks like this:
VERSION="26.04 LTS (Resolute Raccoon)"
Thatâs what the Ubuntu Pro client looks for. But donât forget to connect the Desktop Security Center to the proper plug, afterwards.
the easiest workaround, till base-files is released, is to apply pro via the CLI. the above could do it, or just manually editing /etc/os-release to add the value. Youâll end up with a prompt on package upgrade of base-files asking about which file you want to keep (youâll want to take the package version at that point).
So rather than worry about that file, if you need pro on day 1, until base-files is updated, CLI is easy. Sorry, i donât really use the GUI for such things to know if you can enter the token regardless (i came to Ubuntu first as a sys admin, only using desktop after 5+ years of doing sys admin of Ubuntu from a MacOS laptop. it was that or Windows at $OLD_JOB for laptops)
Thank you for the replies.
I wanted to share a screenshot of the issue for better clarity.
In the Security Center, Ubuntu Pro shows the message:
âUbuntu Pro is not available for this Ubuntu releaseâ
and
âAn LTS release is required for Ubuntu Pro.â
So at the moment, it does not allow activation through the graphical interface.
Based on this, do you think I should simply wait for an update / fix in the Security Center Snap, or would you recommend trying another method such as terminal activation?
I would appreciate your advice on the best approach.
Iâve updated my previous comment with some additional explanation. Combined with the one before that, you should be able to use the Desktop Security Center to attach your machine to your Ubuntu Pro subscription.
@peterwhite123 I edited my /etc/os-release to show VERSION=â26.04 LTS (Resolute Raccoon)â but desktop-security-center insists
Youâve left out the most vital step, connecting the desktop-security-center snap to the obersve-system plug. Consider the Security Center as having a blindfold on until you do that.
I can only remind people so often 
Thanks for the suggestion, can confirm this alone fixes the problem. I guess its just a snap permission issue for the security center app. I could activate pro from the terminal using the token with no issues.
