System is running without any issues but upgrading it not working. I'm on js-controller 3.2.16 and if I execute iobroker upgrade self I get the following output:

pi@iobroker-pi4:~ $ iobroker upgrade self
No connection to databases possible ...
 redis get system.host.iobroker-pi4.alive, error - Connection is closed.
No repositories defined.
Cannot get repository under "undefined"

iobroker repo list 
iobroker update

And please keep your nodeJS installation up-to-date.

Thanks @thomas-braun, sadly this didn't help.

pi@iobroker-pi4:~ $ iobroker repo list

Maybe there is still something running in the background?

ps aux | grep ^io

[miggedy]

No, nothing is running anymore. That command doesn't return anything.
Maybe also interesting:
While iobroker is not running, these commands also fail (but work if iobroker is running):

 pi@iobroker-pi4:~ $ iobroker repo list
No connection to databases possible ...
Cannot get list: Error: Connection is closed.
pi@iobroker-pi4:~ $ iobroker upgrade
No connection to databases possible ...
No repositories defined.

Not sure if this helps but try jumping to the version you want to have:
3.3.5 is beta-stage:

Controller "js-controller" : 3.3.5    , installed 3.3.5

Try

iobroker stop
cd /opt/iobroker
npm install iobroker.js-controller@3.3.5
iobroker start
iobroker status

I tested the manual installation @thomas-braun mentioned (npm install...) and this worked. I'm now on 3.3.5 and running iobroker upgrade self now doesn't show any errors anymore (just that it's up-to-date).

In case this happens again for the next update I will try the different repo @crunchip mentioned.
Thank you both for your support.
