I removed entry for serviceapp from /var/lib/opkg/status then opkg install enigma2-plugin-systemplugins-serviceapp

It is present in the feed:

-rwxrwsr--. 1 root openpli  154400 May 11 00:18 enigma2-plugin-systemplugins-serviceapp_1+git161+02956ea-r0.10_osninoplus.ipk

I see no attempt to download it in the logs, so maybe you need to specify the correct package explicitly:

opkg install enigma2-plugin-systemplugins-serviceapp

or simply install it from the plugins menu.

Same error:

Can I download ipk from any URL directly ?

This is my version:
