I tried both by direct command / ssh or through the webinterface, it gives an error when doing the migration because of the system not up to date

is there a way to force the migration ?

Can you share the output of apt policy libzstd1

$ sudo apt policy libzstd1

Theeeeen let’s try to apt install php7.3-redis libzstd1

[olm_e]

already done hat actually (first part of my message)

ok so I see that libzstd1 version 1.4.8+dfsg-2+0~20210302.3+debian9~1.gbp8effd2 is available so I forced it installation with

$ sudo apt install libzstd1=1.4.8+dfsg-2+0~20210302.3+debian9~1.gbp8effd2

then reinstalled php7.3-redis
then relaunched the migration and it pass the step …

thanks, hope it helps if some other fall on that small hole too

(edit : I also had added the buster-backport in the /etc/apt/source.list … maybe it helps for that version being available … )

(edit 2 : migration to v4 went all good after that )
