Upgrading from Proxmox VE 8 to 9, Debian 12 to 13, PBS 3 to 4, and LMDE 6 to 7

Proxmox VE 9 has been out for a while, and it is based on Debian 13, which has also been released for a while. However, other than my main server (a ML110 Gen9) running on Proxmox VE 8, all other parts of my homelab are not standard installations. My Proxmox Backup Server has a concurrent Proxmox VE installation. My Fujitsu Celsius M740 Proxmox workstation that was installed with XFCE desktop on top of Proxmox VE 7 originally. For my main workstation running on a Ryzen 7 5700G, I had previously installed Proxmox VE 7 on Linux Mint Debian Edition 5 and then dual upgraded it from Proxmox VE 7 to 8 and Linux Mint Debian Edition 5 to 6. It was going to be painful to upgrade all of them to the latest version of Proxmox VE and Debian/LMDE.

 

Still, I knew I had to do it, and with a bit of time yesterday, I steeled my resolve and went ahead.

 

I used the official guides and my previous attempts as references.

Upgrade from 8 to 9 (for Proxmox VE)

Upgrade from 3 to 4 (for Proxmox Backup Server) 

Upgrading workstation to Proxmox Virtual Environment 8 

Dual upgrade: Proxmox 7 to 8 and Linux Mint Debian Edition 5 to 6

 

The actual upgrade process was more a case of changing the source.list files in /etc/apt so that they use trixie (Debian 13) instead of bookworm (Debian 12), and gigi (LMDE 7) instead of faye (LMDE 6). After which, I ran

apt update

apt dist-upgrade  

Once again, repeated use of 

apt -f install

dpkg --configure -a

apt dist-upgrade

helped me to finally get everything upgraded.

 

 

 

The main server seems to be running stably on Proxmox VE 9 with Linux kernel 7.0.6. However, the main workstation with Ryzen 7 5700G suddenly rebooted while on kernel 7.0.6. So, I decided to roll back to kernel 6.8.12, which was previously running fine when it was on Proxmox VE 8.

 

 

 

The backup server seems to be fine too.

 

 

 

The Fujitsu workstation is not used much, so I am not sure how stable it is.

 

Also, for the workstations, given that they have the LMDE repos installed due to my love for having Linux Mint icons, I faced the same issue where Proxmox does not recognise the version codename "Gigi" (which is LMDE 7). It causes the error message "unknown Debian code name 'gigi' (500)" and so I had to edit /usr/lib/os-release and change

VERSION_CODENAME=gigi

to

VERSION_CODENAME=trixie 

 

I guess I should not have to do this again, hopefully, for a couple years more.

Japan premiere of Sparks of Tomorrow (二十世紀電氣目録-ユーレカ・エヴリカ-)

 

Today, I managed to catch the Japan premiere of Sparks of Tomorrow (二十世紀電氣目録-ユーレカ・エヴリカ-), the next TV anime series from Kyoto Animation that is loosely inspired by a light novel published by Kyoani. It will start airing on TV and streaming services from July 2026. The Japan premiere included a stage event with the voice actors of the two main characters (Sakamoto Kihachi, voiced by Uchida Yuma, and Momokawa Inako, voiced by Amamiya Sora) as well as the director, Ota Minoru.

 

While Kyoani did publish a light novel titled 二十世紀電氣目録, it seems that the anime series is only loosely inspired by the original work, and therefore, it is anyone's guess how the story will pan out. Basically, the official website says:

 

A Tale of Adventure for Boys and Girls
Who Dreamed of the Age of Electricity
in a World Shrouded in Smoke!

A little while ago.
Kyoto in the early 20th century, having evolved differently from the history we know today.
In a world where only steam engines had advanced, the city was shrouded in smoke.
──A little while ago. Kyoto in the early 20th century, having evolved differently from the history we know today. In a world where only steam engines had advanced, the city was shrouded in smoke.
With challenging art backgrounds reminiscent of Impressionist paintings and intricate animation, it depicts the dreams of boys and girls shining in an era of upheaval and innovation.
Kyoto Animation's new frontier.

From the way it is being promoted, it seems that Kyoani is trying to position this as the next Violet Evergarden.

 

Except for me, it wasn't. 

 

The background art was very well done, and the animation was Kyoani class. But that's about it. The Japan premiere showcased episodes 1 to 3 of the TV series that will be aired in July, but the story failed to draw my attention. The characters were deformed sometimes to exaggerate expressions, but instead of adding to the artistic expression and direction, it felt more like a cheap comedy trick most of the time. For around 67 minutes (the length of the premiere), I couldn't help but feel it was trying to copy Miyazaki Hayao and Shinkai Makoto in some weird mash-up that simply failed to hit home.

 

The music used for the series also felt generic, like something you have heard elsewhere. I don't even remember it now. I don't even have much to say for the story because it felt like another boy-meets-girl generic romcom, except that it is set in some steampunk alternate Meiji-era Japan, using the kanji 明滋 instead of 明治 for Meiji to show that it is an alternate timeline. The last 10 to 15 minutes was so uninspiring that I was more or less dozing off, just waiting for the show to be over so that the stage event could begin.

 

 

The stage event was also very generic. The voice actors talked a bit about the recording, director Ota said he was chosen as director because he volunteered. I was hoping to hear more about how they went about formulating the (uninspiring) story or working on the soundtrack, but the director was shy and never really talked. In the end, I treated myself to a Whopper Jr. at Burger King as a way to make it up.

 

On the way home, the words from the recent episode of Akane-banashi came into mind. "Support is gained after you've displayed your art. If such support precedes your art, that's proof of your immaturity." Kyoani has pushed out many great works in the past. Even after the arson attack, Kyoani pushed on, and fans continued to show their support. We kept believing that the Kyoani we knew will return. But is that support really support, or something mixed with pity?

Finally, dark mode

After so many years, finally, there is dark mode on this blog.

 

Given that I haven't touched the template of this blog for many many many years, it was a challenge to add dark mode. In the end, I gave up, and asked Claude to do it.

 

Now, the blog will load in either light or dark mode, depending on your system's settings. There is also a toggle at the lower right of the screen to force it to switch modes.

 

In the midst of this change, I also realised that the blog has been on default mobile settings, which meant the desktop template was not being used when viewed on mobile devices. I have also fixed that.

15 years since the Great East Japan Earthquake of 11 March 2011

15 years have passed since the Great East Japan Earthquake and its resulting tsunami struck Japan on 11 March 2011.

I still cannot forget watching the news that day.

 

I still cannot forget the experience of living in Tokyo for a year after the earthquake, with the frequent aftershocks and an entire nation dealing with the aftermath. And how the movie Suzume strikes such a chord in my heart.

Welcoming the Year of the Fire Horse

Happy Chinese New Year! 新年快乐！ Today marks the first day of the Year of the Fire Horse, or 丙午, and what better way to celebrate than to post some stuff written for this day!

 

The couplets for this year reads

蛇行福起

馬到功成 

 

I also wrote the characters for 馬、福、吉、祥 and used GIMP to give them a red background.

 

 

The originals: 

 

 

Once again, happy Chinese New Year! 

 

Watching The Dangers in My Heart: The Movie (劇場版「僕の心のヤバイやつ」)

I really liked the anime adaptation of The Dangers in My Heart, and when they announced a movie, I was very excited. Somehow, I overlooked the part about it being mainly a compilation film, rather than a proper sequel.

 

However, even though 95% of the film was mostly from the TV series, it was very nicely compiled to show the story of the relationship between the two main characters, and Ushio Kensuke's music really added a lot of emotional impact. Just the amazing soundtrack itself was worth watching this movie in a theatre.

 

Movie-goers were even given this small booklet with a short story drawn by the original manga author.

 

I really hope they will make a sequel to this series because the story is really a nice, heartwarming one. I could read the manga. But I want the music by Ushio Kensuke!
