It takes me an all afternoon, but the upgrade went very clean and smooth for the first of my 3 laptops, the oldest one. Some "foreign packages" (but not all of them) have been kicked out (I didn't do it), but were easy and quick to reinstall. LM20 is quick, light, and, as always, beautiful.
Many thanks to Clem and the team !
Back soon for the feedback of two others upgrades... (cross fingers)

The tutorial was moved to the user guide. A new section was added to purge PPAs in the preparation step. Another section was added for troubleshooting and to bring solutions to frequently asked questions.

I believe the machine lost contact with the internet. Certainly, on exit from the procedure, I could not access the internet. My internet access is through WiFi: Bus 002 Device 003: ID 0bda:8179 Realtek Semiconductor Corp. RTL8188EUS 802.11n Wireless Network Adapter
via a Vodafone WiFi hotspot.
Can you advise me how to progress, please.

Thanks for the upgrade path and the instructions! My experience and feedback: I've just completed the upgrade. No special issues, however, as upgrade took MANY HOURS, would have preferred a section above describing preferred scenarios. Time and energy considerations would make a clean install preferable! Next, the scenario's described above do not cover some of the paths during upgrade that might be better to shed some light upon. I am pretty unexperienced to might have misunderstood: As i had the "Swap" in encrypted mode (as i tend to choose "encrypted" when possible as a principle), in the "pre-run" as i understood a non-encrypted one was created. However, during the real upgrade, i saw several mentions of "swap missing" which in turn might be the reason the upgrade took so long.. Hopefully this feedback helps to create a better and more fluid instruction & upgrade for others! ;-) wkr, Frans

I found the upgrade somewhat a problem. After 2 hours of upgrade I realised it was repeating the upgrade. As this machine only drives my TV systems I decided to stop it and do a full install which takes far less time. Found that Mint 20 was there on reboot, so I ran the Foreign downgrades. So many of them???? Scary what was going to happen as Google Chrome was my only addition to the mint 19.3 system. Time will tell if everything works or not. Overall it was NOT a smooth transition like mint 18 to 19 was.

Sorry, too buggy and too dangerous for main computer install.


www_MKRD_info 1 day ago

Step "D6. Delete foreign packages" is VERY dangerous. I installed on a backup computer. A VERY long list of packages were presented as "foreign". Trying to delete them, I got notifications that some are essential to the operating system and cannot be deleted. Meanwhile, trying to bypass these "essential" packages, and trying to remove others from the "foreign" list, I have now broken my system's ability to remove old kernels.
1) This D6. Delete foreign packages step is dangerous.
2) I need to hear a MUCH BETTER explanation of the meaning of this "foreign packages"'; what they are, why it is that I have to delete them, why are ESSENTIAL packages like "mountall", and why are my "third-party installations" are showing up in the list JUST BECAUSE the upgrader removed all third-party PPAs I have previously edited. Why is that I am being told to remove perfectly good third-party software??? Why does the installer have to wipe out third-party PPA sources I have added during previous software installations? IS THERE A STEP MISSING TO RE-ADD PPA's THAT UPGRADE UTILITY HAS DELETED, MANUALLY, BEFORE PROCEEDING TO THIS STEP???
3) As already demonstrated, I have now damaged my OS (cannot delete outdated kernel images due to a libcrypto issue). https://askubuntu.com/questions/1116133/ubuntu-18-04-libcrypto-so-1-0-0-cannot-open-shared-object-file-no-such-file-o

I DO NOT RECOMMEND THESE UPGRADE INSTRUCTIONS AT THIS TIME. TOO DANGEROUS AND TOO INDISCRIMINATE, WIPING OUT PERFECTLY GOOD SOFTWARE THAT I HAVE MANUALLY INSTALLED PREVIOUSLY FROM THIRD-PARTY PPA's.

Hi Clem and Linux Mint Team. The upgrade was a success. So far so good. Thank you so much for the support.


willendorfer 1 day ago

I tried again, and this time got all the way through the mintupgrade download. To be clear, I followed all the instructions precisely, having updated everything beforehand, pointing to the default software sources, etc, and there was no issue when I ran mintupgrade check. But ... on mintupgrade upgrade (having dropped into console as suggested, the process terminated with an error message as follows:
+Disabling screensaver and power management
cinnamon-screensaver: no process found
light-locker: no process found
Traceback (most recent call last):

raise KeyError(key) from None
KeyError: 'XDG_CURRENT_DESKTOP'

I've spent way too much time trying to troubleshoot this. Unless Clem or someone can explain what the problem is, I'm just going to have to wait for this upgrade.

Nevermind... I just needed to upgrade one of my packages... now it worked


diapason 1 day ago

I have just done the upgrade without difficulty. All seems well. The only issue is there may be a problem with Evolution email. It works normally with my gmail address but it will not now connect to my principal imap address. The error message is "error performing TLS handshake. A packet with illegal or unsupported version was received". Reinstalling Evolution did not fix it. The Mailspring client is working perfectly with all my email addresses but I prefer Evolution so any suggestions will be welcome.

I seriously hope you're not going to say this upgrade is just for Cinnamon, after failing to mention it anywhere on this tutorial page ...

Upgrade from LinuxMint Mate 19.3 to 20 took a while, but worked fine. I had to reconfigure Compiz. Unfortunately, I was not able to get Screenlets running again. I would like to display a monthly calendar sheet and a clock on my desktop, but could not figure out an alternative, so I switched back to 19.3 (also without problems), using timeshift.

Some progress. I managed to downgrade/remove foreign packages by doing each one singly. So far as I can tell everything is up to date and working. Time will tell.


TimSC 1 day ago

I hit another problem with a headless upgrade, it wanted to halt postgresql before upgrading libc6 but provided no safe way for me to stop the service (I could not ssh into the box). Nearly borked the upgrade with that one!


AlanG 1 day ago

It was all going so well then kaboom. Upgrade step ran for 30 minutes then a black screen and the PC dead.
Powered it up and up came Mint 20 but on trying to resume/fix the install with
$ sudo dpkg --configure -a
I ended up with an error which suggested I ran
$ apt --fix-broken install
I tried that and it just printed the apt usage message.
Now stuck.
If I try the Downgrade foreign packages (or remove) I get the same error message.
It seems to be related to python dependencies(see below)

У меня проверка через mintupgrade check проходит без ошибок, а во время установки ругается на то, что не может запустить xdm.service, и просит запустить его вручную через: /etc/init.d/xdm start. Но ни в ручную, ни через systemctl start xdm.service ничего не запускается. Вывод команды прилагаю:

When I check all of the foreign packages installed (from "Menu -> Administration -> Software Sources -> Maintenance -> Remove Foreign Packages") I see there are a LOT of them. I'm able to recognize some of these packages, but I'm not sure about most of them.

So,
- What are the implications of not doing this step?
- What if I remove accidentally a package that is needed by some app later on? Can I recover it? (I guess so, but I'm not sure if it is safe to do so)
- What may be the best way to approach this step?

PS: I asked this here: https://unix.stackexchange.com/q/597716/421977

Hi,
got an Error, the mintupgrade script crashed and i had to do then "Source Rollback" manuel via "mintupgrade restore-source"

Here the Error ( sorry in german )

Works perfectly. My mint version 19.3 was installed a few months ago, that could make the difference.

Upon closer examination, it seems that the upgrade removed the "Docky" application dock, and will not let me reinstall it through the package manager. The "Install/Remove" button never appears, just a spinning "wait" icon.

I can't add the PPA to my list; doing so produces this error:

~$ sudo add-apt-repository ppa:docky-core/stable
Cannot add PPA: ''This PPA does not support focal''.

Downloading the .deb file and opening it produces this error message:

Error: Dependency is not satisfiable: libconf2.0-cil (>=2.24.0)

...and the install button is grayed out.

Is there a way to reinstall Docky, perhaps by pulling the files from a Timeshift backup, or...? I'd also be open to alternative docks.

Hello!

The labelling of steps D5 and D6 suggest that those steps should be performed *after* the upgrade. Is that right, though? Should it not be *before*?


Waylon 2 days ago

Thank you for the very detailed walk-through!
I did the upgrade and everything went fine. It was grinding away for ~35 minutes or so, then a reboot or two, and *boom*, it's done. There are some minor items missing from my Docky dock, but other than that things seem to be fine. And maybe it's just me, but everything seems little snappier now.

The ones who have problems with apt install mintupgrade, you need to go to your update manager and reset the package sources to default. then you will be able to install the mintupgrade package.
