I run 23.05.0 for some time now and do an opkg update
I get (after upgrading upgradable):
root@slate:~# opkg list-upgradable
wpad-basic-mbedtls - 2023-09-08-e5ccbfc6-4 - 2023-09-08-e5ccbfc6-6
root@slate:~# opkg upgrade wpad-basic-mbedtls
Upgrading wpad-basic-mbedtls on root from 2023-09-08-e5ccbfc6-4 to 2023-09-08-e5ccbfc6-6...
Collected errors:
* check_conflicts_for: The following packages conflict with wpad-basic-mbedtls:
* check_conflicts_for: wpad-basic-wolfssl *
root@slate:~# opkg list-installed | grep wolf
libwolfssl5.6.3.e624513f - 5.6.3-stable-1
Somehow I cannot upgrade installed wpad-basic-mbedtls ... I do not see conflicting wpad-basic-wolfssl installed.
