Hi guys, so i have problem with install apache2 on my opensuse. It just shows error “package not found”. I don’t know what to do. Can someone help me?
You only tell what message you got, but nor what you did. And we are no mind readers.
Also, openSUSE 42.3 is very very old and long out of support, thus it would not wonder me when you can not find software for it.
Moved to Applications.
OP should upgrade to the currently supported Leap release, 15.2. Lots of apache2 bugs in particular, and security bugs in general, have been found and fixed since 42.3. If upgrading is not possible, repos should be reconfigured to an archive mirror for releases no longer hosted on opensuse.org. http://ftp5.gwdg.de/pub/opensuse/discontinued/update/leap/42.3/oss/x86_64/ is one location providing latest apache2 for 42.3.
Another option would be upgrading to 15.3 beta, due for release in around 6 weeks.
What versions will work for my openSUSE? Sorry, but i’m completely new in linux.
The most efficient way forward would be to replace 42.3 with a fresh installation of 15.2. If 42.3 was installed using a separate filesystem (usually on one partition separate from / or root), then the /home filesystem on partition can be kept intact, and only the openSUSE operating system itself would be replaced by a fresh installation. Officially, upgrading is only supported and thus tested officially between sequential versions. For you that would be from 42.3 to 15.0 to 15.1 to 15.2. It’s doable, but could take a lot longer than doing a fresh installation. https://en.opensuse.org/SDB:System_upgrade documents how to proceed with an upgrade using the live method that I use almost exclusively.
