I've had Not all updates can be installed problems with Software Updater for quite some time. Now it has gotten to a blank screen with a large download of (blankety-blank-)blank. Running Software Updater gets:

Checking for Updates...
Updated Software is available for this computer...

However, the Details of updates and Technical description sections are blank. Yet it says that 331.5 MB will be downloaded.

Here is a screenshot:

Software Updater not showing

So am I expected to download 300+ MB of secret files, so secret they have no names?

I have been dealing with Not all updates can be installed for some time. Searching seems to imply this is a problem with the repositories or package dependencies, and to wait until they get straightened out - but MONTHS of waiting?

The only suggestion Software Updater offers is a Partial Upgrade (to what? Release 21.666.7734?) but I use LTS for a reason: I don't want Upgrades every week (or even month); I do not want to be a member of the Bug-Of-The-Month Club, and some other postings indicate the Partial Upgrade is a bad idea.

Nothing offers any clue as to what is wrong. Synaptic shows
86901 packages listed, 25535 installed, 0 broken, 0 to install/upgrade, 0 to remove and various suggestions from searching seem to be "turn the software loose and trust us" such as sudo apt-get upgrade and hope the stuff that's not working fixes itself...

If we can't depend on and trust the software that is updating our systems, we're in trouble. How do I get out of this trouble?

Here are my OS details:

  • Ubuntu MATE 20.04.6 LTS (Focal Fossa) 64-bit
  • Kernel Linux 5.18.10-76051810-generic x86_64
  • MATE 1.24.0

Not wanting to run sudo apt upgrade until the problem is at least diagnosed, if not fixed, since it makes changes as it wishes. With the Software Updater failing (blank list for 300+ MB of changes), more changes can make things worse.

    Please edit your question to show us the complete output of sudo apt update and of sudo apt upgrade. Keep in mind that we are your peer users and volunteers -- avoid hyperbole and shouting and rhetorical questions, as it scares away knowledgeable folks who otherwise could help you.

    The MATE desktop is a flavor and is EOL as is no longer supported by the Ubuntu MATE team (ubuntu-mate.community/t/…) so there are no updates there. You're details show you using a non-Ubuntu managed kernel (it was a testing kernel only in Ubuntu) from 20.10 which has long been EOL & thus isn't supported. What are you running? as your kernel is non-Ubuntu which could be reason for your issues, are you using Ubuntu?

    5.18.10-76051810-generic is not a Ubuntu kernel but a POP OS kernel used by Pop OS created by System 76 (as encoded within the kernel details). The 5.18 kernel was used by Ubuntu 20.10 which is EOL though also used by 20.04 using HWE, but Ubuntu systems upgraded to 20.04.3 prior to 20.10's EOL & thus weren't using 5.18 any longer. If your system was Ubuntu at install, it's now been polluted with Pop OS and thus your issues; you've turned your system into a frakensystem most likely

Got it! It was a problem interacting with the System76 PPA. I unchecked just that PPA and both problems disappeared: the Software Updater gives a proper update window, and does not have the Not all updates can be installed issue nor anything about a Partial Upgrade.

Still running kernel 5.18.10-76051810-generic, so I will have to figure out how to get over to the correct kernel; several postings deal with that problem.

I will email this information to System76 support. We can hope they can figure out what's wrong with their PPA.

(Question for guiverc - how did you know that was not an Ubuntu-MATE kernel, and where can we find such information/documentation? And Thank You very much.)

    Ubuntu 20.04 LTS provides 5.4 as the GA kernel, which is the default for flavors (ie. Ubuntu MATE) at 20.04 & 20.04.1, with later media using the HWE kernel stack (20.04.2 & later). At 20.04.2 the 5.18 kernel from 20.10, which is changed to 5.11 at 20.04.3 (from 21.04), 5.13 at 20.04.4 (from 21.10) & finally ceased upgrade at 5.15 at 20.04.5 (5.15 being the GA kernel stack of 22.04). Other OEM kernel options do exist; but your details showed a System 76 (76051810) rather than Ubuntu code. See wiki.ubuntu.com/Kernel/LTSEnablementStack for some HWE details if useful

I don't know how to solve the bug with the software updater not displaying the available upgrades. However, you can see the available upgrades from apt list --upgradable, and it is completely safe to upgrade via the command line.

You can use the command sudo apt full-upgrade, so that Ubuntu installs all the updates available for your particular release, but does not upgrade (or partial upgrade) to a later version of Ubuntu.
