Site offline with 500 Internal Server Error after update from 2024.12 to 2026.01.

Hi there,
after succesfully updating the site several several times lately, trying to get it to run friendica stable the last update just got stuck.
Calling the site gives 500 error message.
In a first attempt to trouble shoot the situation I did the follwoing.
I stopped the cron job by quoting out the respective crontab -e line.
Than I tried to set the site into maintanence mode by using the description as detailed in forum.friendi.ca/help/admin/mi…:

bin/console maintenance 1 "We are currently upgrading our system and will be back soon."

As update procedure I used the standard procedure:
git fetch
git checkout
Your branch is behind 'origin/stable' by 2025 commits, and can be fast-forwarded.
git pull
cd addon
git fetch
git checkout
Your branch is behind 'origin/stable' by 226 commits, and can be fast-forwarded.
git pull

Any idea what I can do to solve this?

i've been researching the correlation between console name numbers and console sales numbers.

• consoles with 1 in the name have a middling sales record (PS1, xbox one)
• consoles with 2 in the name sell really well (PS2, switch 2)
• consoles that are a correctly numbered "sequel" to another console sell great (PS2 & switch 2 again, PS3, PS4, PS5)
• "sequel" consoles that don't use a number sell terribly (wii U, xbox series X|S, PS vita) unless they are boys (game boy et al)
  
  • however, you can only release three boys (game boy, colour & advance). further boys will not sell (virtual boy). numbered boys are as of yet untested

  
  

• "sequel" consoles using the wrong number sell quite well, with higher numbers moving more units (nintendo 64, xbox 360)
• "sequel" consoles can skip a number and still sell well if they put the number at the front, but will never reach the sales numbers of their predecessor (3DS)
• consoles that aren't a "sequel" yet still use numbers sell abysmally, especially if the number's at the front (turbografx 16, 3DO)
  
  • this actually worked once (atari 2600), but caused the north american video game crash and doomed the company, no matter how high they tried to make the numbers (atari 5200, atari 7800)
