I’m trying to upgrade ubuntu unity 24.04 LTS to ubuntu unity 26.04 LTS (sort of an LTS), retaining all my Apps. I just want to confirm that I’m doing it the right way.
I’m not sure what the point is but you don’t give any information on what you mean by ‘my apps’. Is this 3rd party software? If you install 26.04 to the same partition(s) on which you have 24.04, it will overwrite everything. So what exactly are you going to restore from your backup, personal data, 3rd party software?
My 24.04 is very customized with apps (libreoffice cutom menu bars, Nemo , jedit, arahnophilia, CairoDock, cherrytree, surfshark, oracle virtual machine, sqlitestudio, bluefish, masterpdf editor, flameshot, dlume, qualculate, filezilla, Konsole, thunderbird mail, alacarte/menulibre, and a bunch of other goodies that I can’t think of right now).
To re-install all of these on an ‘empty’ 26.04 is a lot of work. Basically, I would like 26.04 to ‘look and work’ like my 24.04.
I have been re-thinking my above plan to do this, and I’m not sure it is the right approach. Would the above plan damage 26.04 ?? Would I be wiser to just transfer my Home Directory and etc ??
A few years back I had to start with an ‘empty’ OS (I think 20.04) and copied my Home and etc directories, but that still left me with a lot of work to make the new OS ‘look and work’ like my original Desktop.
What is the best way to get 26.04 running with all the software from my 24.04 ??
Is there any particular reason that you do not want the system to simply handle the upgrade for you ? Within the next week or two you should get this offered automatically anyway
I have tried the upgrade and it failed with the dreaded Kernel Panic when I booted into 26.04.
I have had problems with regards to a Kernel upgrade from 6.14 to 6.17 - this led to a Kernel Panic, forcing me to restore from a backup and staying with Kernel 6.14. I’m not sure if this is related to why I cannot do the system upgrade which would sure be nice.
Your actual problem is some vague failure about an upgrade you tried.
But instead of asking about that, you are asking for folks to review some other entirely different method of haywiring a backup from an older version of Ubuntu onto a fresh install.
There is no perfect method to haywire an old backup onto a different-version install. Likely some of it will work and some of it won’t.
I thought my question was pretty simple.
I’m running ubuntu unity 24.04 and I want to upgrade to ubuntu unity 26.04. I want the 26.04 to have the exact functionality of my 24.04.
I tried usingthe the Software Updater program to upgrade my 24.04 to 26.04, but it failed with a kernel panic.
So the only way I can upgrade to ubuntu unity 26.04 is to do an ISO install, and then try to get all my software (libreoffice cutom menu bars, Nemo , jedit, arahnophilia, CairoDock, cherrytree, surfshark, oracle virtual machine, sqlitestudio, bluefish, masterpdf editor, flameshot, dlume, qualculate, filezilla, Konsole, thunderbird mail, alacarte/menulibre,…) installed.
The safest way to get 26.04 along with 24.04 is to create unallocated space on which to install 26.04 and then make the changes to your software as time permits. 24.04 will be supported for 3 more years so there is no rush unless you have something you want with 26.04.
You might be able to install 26.04 over 24.04 and select to NOT format the / and /home partitions and your personal data should not be affected and 3rd party software should not be either. If you use this method and install software that comes with a standard Ubuntu (Libreoffice) it will be overwritten. If you have modifications to various software, make a copy of the configuration files to use. I’ve done this several times with another Linux and once with Ubuntu but I didn’t have a lot of 3rd party software installed.
Do you recall at what point during the release-upgrade the kernel panic occurred?
During calculating the upgrade?
During downloading?
During installing?
During updating the snaps?
When rebooting into the new kernel?
I encountered Kernel Panic when booting into 26.04 after the installaion was complete.
I have previously encountered a Kernel Panic on 24.04 when the 6.14 kernel was updated to 6.17. This was related to Broadcom and Virtual machine. I restored to an earlier backup and updated Broadcom and Virtual machine and then, in a panic, deleted some Kernel headers. My bad.
As a result, the software updater no longer brings in a newer Kernel so I’m stuck with a no longer supported Kernel 6.14. This now leads me to Package Operation Failure when I attempt a to run Software Updater. I have a current post on this matter.
Since I will be building a Linux Tablet and updating my wife’s laptop from my Desktop, I have to get my act together and get my Desktop to 26.04.
Did you try selecting an older kernel at GRUB to boot into 26.04?
Most Linux distros (including Ubuntu) keep an older kernel or two just in case exactly this happens.
Restoring kernel headers should be fixable by reinstalling the appropriate package. We will get there.
That’s usually easily fixed via the package system also. We will get there too.
A link to your older post might help.
You have a choice here:
A) You can try booting 26.04 from an older kernel, and then we can help you repair the system, or
B) You can restore your broken 24.04 system from your backup and repair it before upgrading to 26.04.
I tried having Software Updater install 26.04 once again - with the same results.
The installation completes and boots into unbuntu and asks for my password. The request is dimmed, and will not ‘listen’ to my repeated attempts to enter my password. However I can select the gear icon and it displays various options like unity or ubuntu. Regardless of what I select, the system will not allow me to enter anything for password.
So I boot manually - and I get the Kernel Panic:
vfs unable to mount root FS on unknown block(0,0)
I can boot into grub. Is there anything I can do here to bring the 26.04 system up ?
I have been playing around with grub and have managed to boot using these commands:
set root=(hd0,2)
linux /boot/vmlinuz-6.14.0-36-generic root=/dev/sda2
initrd /boot/initrd.img-6.14.0-36-generic
boot
Note that 6.14.0-37 generic worked but the top menu bar was missing all kinds of ‘things’ like alacarte.
ANY idea why Kernel 7 won’t work, and will there be newer Kernel 7. versions ??
lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 26.04.1 LTS
Release: 26.04
Codename: resolute
26.04 looks like my 24.04 desktop which is what I want. However, there are 2 major problems and 3 minor problems:
Major
ethernet is not working & no wifi options shown (broadcom driver ???)
A Data Partition has ownership issues with jedit & libreoffice. In “Disks”, when I do a Filecheck of this partition, I get - udisks-error-quark,3
when I look at Permissions in Nemo, it says unable to determine
Minor:
4. when inserting a USB, the icon doesn’t display on screen - just sidebar
5. alacarte icon is shown twice on top menubar
6. qualculate doesn’t work (I will try re-installation)
I will try to resolve these problems - very tricky as there is no internet connection. Any help especially with the major 2 problems will be greatly appreciated.
I have done the Software Updater upgrade which led me to a Kernel Panic (see above). However, as I’ve said above, I have managed to boot 26.04 with an older Kernel -6.14.0-36. I would like to boot with Kernel 7.
I’m not sure why the kernel panic on the 26.04 upgrade. Maybe it’s the old Broadcom issue??? It would appear to me that others may get a Kernel Panic on the upgrade as well.
It would be nice if the powers that be would look into the Kernel Panic problem.
Thanks for the ls -l tip. I will be booting 26.04 shortly and give it a try.
