Just got an update to the Mint Upgrade app.
Under 'edit' you now have the upgrade from 22.2 to 22.3
Not that I'm doing it today.
Thank you for the 'heads up'.
I'm running Linux Mint on my old 24 inch Apple iMac
I have, this evening, updated to Linux Mint 22.3 Cinnamon 64-bit
So far I've experience no problems. EfOe
Just upgraded too, no-a problems so far and the System Information is
nice. However I'm not too fond of the new start menu. Guess I'll get
used to it eventually...
I confess that I had a 'double-take' at the new start menu too! Efye
Not a problem though.
It's a lot like the cinnamenu applet in 22.2.-a-a I've been using that for
a few weeks.
Thanks, Alan.
Today I've installed Linux Mint 22.3 on my aging 27 inch iMac.
Here's the outcome:-
1. Boot and Filesystem rCo All Correct
From your output:
/ mounted from /dev/sda2 (ext4)
BootCurrent: 0000 raA Ubuntu (shimx64.efi)
BootOrder: 0000,0080
Filesystem state: clean
This means:
You are booting from the internal spinner (sda2) exactly as planned.
EFI is configured correctly: Linux is first, macOS external is second.
Filesystem is clean and consistent.
So from a software and boot perspective: your Mint installation is
properly deployed.
2. Disk Health rCo Usable but Ageing
SMART overall result:
SMART overall-health self-assessment test result: PASSED
However, the deeper stats tell the real story:
Key facts:
Power-on hours: ~29,173 hours (over 3.3 years of continuous runtime)
Start/Stop cycles: 31,050
Power cycles: 62,650
Temperature: ~41-#C (acceptable)
Concerning indicators:
Reported_Uncorrect = 56
SMART Error Count = 56
Multiple historical UNC (uncorrectable) read errors at the same LBA
Very high read/write totals (this disk has been heavily used)
There are no current pending or reallocated sectors, which is good. But:
This disk has already experienced real, logged read failures in the past.
It is well into rCLold agerCY territory mechanically.
It is stable today, but statistically not trustworthy long-term.
In business terms:
Serviceable, but not strategic.
3. Practical Recommendation
Your Mint system is:
Technically correct
Cleanly installed
Booting properly
Hardware mostly healthy
But your internal drive is:
Old
Heavily used
With a history of read errors
You should:
Keep good backups.
Avoid storing irreplaceable data only on this disk.
Plan to replace it with an SSD if you intend to rely on this machine.
If you move Mint to an SSD later, you will gain:
Dramatic speed improvement
Much higher reliability
Lower heat and noise
Final Assessment
Linux Mint 22.3: Correctly installed and operational
Boot configuration: Correct
Filesystem: Clean
Hardware: Fully supported
Disk: Aging, usable, but on borrowed time
*Your system is working*.
*Your disk is surviving*.
