On Mint 21, several services fail

[BeyondLies_MintForum]

I upgraded Mint 20.3 Cinnamon to Mint 21 Cinnamon. I notice that, thereafter, several services fail. I do not know what those services do. Can anyone shed light?

Code: Select all

$ sudo systemctl --failed
  UNIT             LOAD   ACTIVE SUB    DESCRIPTION                                     
● ua-timer.service loaded failed failed Ubuntu Advantage Timer for running repeated jobs

I saw similar messages for a service called 'casper-md5check' (but I reset that service and so do not expect to see the error message until I reboot and run sudo systemctl --failed again). I think there was some other service - another one to do with 'casper'? - affected too.

Were the services working in 20.3? What process did you use to upgrade? Did you use https://blog.linuxmint.com/?p=4378

@deepakdeshp

Thanks for the reply.

I performed the update via the mintupdate program.

Before the update, those services were either (1) absent or (2) working. For, I have a script that tells me periodically if any service has failed; and on Mint 20.3 that service was reporting no problem.

I suggest a fresh install of 21 for testing. Installing in a Virtual machine would be easy and painless,provided your hardware can run 2 oss concurrently.
Best luck.

I compared my service situation, on Mint 21, with a PC running Mint 20.3. (That latter PC runs well but has been fairly severely tweaked.)

I found that, on Mint 20.3, the following failing-on-21 services were enabled and running.

ua-timer.service
casper.service
cgconfigparser.service
cgrulesgend.service.

Now, Mint's Clem seems to say that the caspar service can be disabled safely. I inferred from that - and admittedly it is a bit of leap - that I would try 'masking' all of those services on Mint 21. So I did this:

Code: Select all

sudo systemctl reset-failed
sudo systemctl mask --now ua-timer.service
sudo systemctl mask --now casper.service
sudo systemctl mask --now cgconfigparser.service
sudo systemctl mask --now cgrulesgend.service.

I will see whether everything works.

If everything is working as per expectations,why bother about failed services?

Hello, many people ask, after updating the system to version 21. On my laptop, 10 percent of the programs do not work!, I will write a new topic in time, there are many questions..!

[deepakdeshp]

In version 21 some programs installed earlier from a ppa may not work. May take time for the developers to let it to Mint 21.

'If everything is working as per expectations,why bother about failed services?' Here is why. The failure of a service might indicate a problem. It is because failed services might indicate a problem that I have my computer tell me if and when there is a failed service. (I have a lua script that works with a conky.) If I start ignoring such warnings, then the warning mechanism becomes useless.
