i rolled back wget and tmux to previous versions but didnt help.
After also downgrading curl rpm, dnf funcionality was working again, see below:

Is this ok [y/N]: n

After that i dnf updated all packages, so curl was reverted to latest version as well as the others and dnf is working again no problem and all are updated.
i would expect though that on first update of curl all the required dependencies would be sorted out by dnf itself and dnf wouldnt break, so any idea what happened?
Let me know if you need more output.
