The Linux Mint 21 distribution exit with long -term support (LTS) took place on August 1, 2022.
In mid -August, I made a transition from 20.3 "Una" на 21 "Vanessa"..

Introduction

Unlike previous distributions, which were updated by the standard utility "release-upgrade ",
which appeared after the release of the new version of the OS, a new update tool was created to go to Linux Mint 21 "mintupdaTe ", with which the update is made by just a few clicks of the mouse in the graphic interface.

1) Preparation for the update. I recommend updating packages until the latest versions

sudo apt-get update
sudo apt-get full-upgrade

Then, I recommend it in front of UPGrade OS execute the following point at number 2:

2) in the program "Start" - "Parameters" - "Sources of Appendices" Disable the PPA -Raisor ,
without which you can do at the time of the transition. PPA repositories can be connected back after switching to version Vanessa.

After disconnecting the PPA, click OK in the window with the message "The configuration is changed. Click OK to update Kesh APT"

3) Installation of the tool "mintupgrade " for updating Linux Mint:

sudo apt-get install mintupgrade

4) launch "mintupgrade " to start updating the OS.

sudo mintupgrade

Greetings window: "Update to Linux Mint 21 Vanessa":

5) Immediately I recommend turning off the creation of pictures - although this is a risky step, but saves a lot of time.

Disconnecting the creations is performed in the "hamburger-manager" (button with three horizontal stripes).
In the window, I turned off the item "Recent Timeshift"

6) Return to the previous window (pressing the cross) and click the "Come!"

7) Этап 1. Подготовка

Click ok .

APT Kesha checks.

If it is impossible to connect to one of the sources of applications,
the problem will be reported, and it is proposed to disable this source,

for example: if "Deb: //librewolf.net" is not available. Press "fix" .

Other users may not have the indicated problem, then the transition to the next stage will take place ..

8) in “sources of applications” - “mirrors” by default the nearest and fastest servers in Russia for the previous distribution "20.04 una" .
But for the duration of the update they will be disconnected! Repositories for the duration of the Linux Mint update switch to servers. on which a repository for Linux Mint 21 "V is storedanessa", i.e. foreign servers.

It is necessary to click on the “main (UNA)” with the mouse - the server searches and the ranking of their speed will occur.

I chose the main one of the repositories with a good access speed - in this case, the Central Linux Mint repository in the USA.

He also clicked the mouse on the list "Basic (FOCal)" выполнил такие же действия. Выбран сервер ubuntu.mirror.constant.com

After changing the mirrors, the following view of the window “Sources of Appendices” - “Official Repositories” - “Mirrors”:

I pressed the ok button to continue. The update of temporary files (Kesha) began.

9) In "additional repositories" he took off all the checkmarks except Yandex disk.

10) clicked on the "cross" in the window header "Applications Sources", the update of the system continued:

Search for third -party packages:

A window was displayed on the presence of packages, which have a rollback of the version number.
"Third -party packages. For the next packages, a rollback should be made to the official versions"

Further, I leaf through the list down (for familiarization):

Further, I leaf through the list down (for familiarization):

11) At the bottom, press the red button "fix" :

After that, versions of the packages will be given to the required.

Then, for the same purpose - bringing to the right versions, Search for third -party packages will begin **.

12) In the next window, the list of " unused packages" , which are absent in new repositories (i.e. repositories "v, will be displayedanessa":

I leaf through the list down to familiarize myself with which packages are absent in the new version ...

Click "fix".

13) Этап 2. Имитация и загрузка пакетов

You expect a long process, but almost immediately a mistake arose: "It was not possible to correctly update your packet cache. Execute" apt update "and correct the mistakes that the team will show" .

Following this advice, he launched the Terminal program and completed

sudo apt update

It is necessary to remove the packages on which the program will swear. As usual - sudo apt remOve

We repeat the process of verification and the "point" removal of packages - until this error disappears.

Check again

Finally, the program will stop finding mistakes and will allow to continue the update:

Check again . There are no errors:

14) The process of simulating the update will begin.

15) After checking before the update, a detailed report on the upcoming changes in the system will be displayed: the load volume of 4.1 GB, an additional place of 3.8 GB will be required. 3521 packages will be updated and 695 new packages will be added, 81 unnecessary packages will be removed (old versions, etc.).

16) After pressing OK, the loading of packages (4.1 GB) will begin.

You can observe the process of loading packages

The loading process is over.

17) Этап 3. Обновление.

I click OK. The update process has begun.

The update is completed successfully:

18) reboot PC.

The loading of the OS is successful.

19) We go to the "Start" - "Parameters" - "Update manager" .

For the presence of a package for updating vkd3d we do not pay attention yet.

You need to switch to a local mirror!
Kesha update is performed again. We carry out updating new packages.

20) It remains to include in the "sources of applications" PPA-references and additional repositories for third-party programs.

Conclusion : Update Linux Mint OS 20.04 to version 21 "Vanessa" it takes place in three stages: " preparation "," imitation "and" update ".

Council for updating to Linux Mint 21 "Vanessa"

In the case of freezing or looping the process, just interrupt it. Then, complete the same team

sudo mintupdate

The installation will continue from the place in which it was interrupted. In my case, the interfering package was proftpd (установка не продвигалась вперед). Пришлось удалить пакет: sudo apt-get remove proftpd. После обновления я установил и настроил пакет prOFTPD again.

What's new in Linux Mint 21 "Vanessa"?

1) Linux 5.15 core:
_Linux 5.15.0-46-Generic #49-Ubuntu SMP Thu Aug 4 18:03:25 UTC 2022 x86_64 x86_64 x8664 GNU/Linux
2) the remaining packages are close to the 22 LTS package base
3) support until 2027
4) Added new Syste servicemd-oomD which controls the situation of lack of memory
5) Blue component updatedmaN and Bluez subsystem for sound Bluetooth
6) Improved support for images for WWW - now WebP is shown in miniatures in the XAPP program.

my experience using Linux Mint 21 "Vanessa"

The system is not much different from 04/20/15 externally. The main changes "under the hood": the process of using the SWAP file with a lack of RAM has almost invisible. With a lack of RAM, GIMP stopped flying out.
After loading, in simple (without advanced programs), the use of RAM is 800 MB. The speed has not changed: a dual -core Intel Core2 4300 (-MCP-) speed: 2160 MHz и SSD диске, операционная система Linux Mint 21 "Vanessa" летает. Видоизменились, стали более красивыми иконки, например, у программы удалённого рабочего стола Remmina.
