Ettercap not installing on iSH

[isums]

Hello,

I tried to install ettercap from this repository: http://dl-cdn.alpinelinux.org/alpine/edge/testing, but ended up with this error:

ERROR: unable to select packages:
  so:libGeoIP.so.1 (no such package):
    required by: libettercap-0.8.3.1-r0[so:libGeoIP.so.1]
  so:libnet.so.9 (no such package):
    required by: libettercap-0.8.3.1-r0[so:libnet.so.9]

Could someone please help?

This is not iSH related in any way and it is even not an issue, but simple lack of dependendencies for a package. You are trying to install individual apk file downloaded from edge repositories manually, but the package has some dependencies. And the dependencies are currentlybavailable only through edge repositories only as well. System isn’t aware of edge reposit You must add „edge” entries to your /etc/apk/repositories (possibly you want them masked under alias - see iSH Wiki for a tutorial, it’s all explained there) and then simply apk update && apk add ettercap (or apk add ettercap@testing in case of masking entries) will install ettercap plus all additional dependencies without any issues.

As an alternative, use alpine’s package search engine: https://pkgs.alpinelinux.org/contents to find out the packages containing missing files (e.g. libGeoIP.so.1 and libnet.so.9) and download them from edge repository in a same way and install individually before installing ettercap, but be aware that they might have some further dependencies to fulfill. Adding entries to apk config and letting apk solve dependencies itself would be far less time-consuming.

Btw please note that on default filesystem /etc/apk/repositories is being overwritten on some occassions, most likely each app update, with iSH’s own repositories (this way it meets Apple Store TOC). As there are already two or three issues opened here with that „issue”, don’t be surprised by that fact. To avoid it, you can install fresh filesystem from Alpine’s website; OR delete /ish/version file from the default filesystem; OR simply edit /etc/apk/repositories and then install desired packages in a row, without closing the system.

@esgie The post I made proves that even after ettercap is installed, it will then turn itself into an iSH problem. Yes I see that the OP missed installing some dependencies but there is insufficient data supplied as to the actual method of having lost them. Your guess was equally as good as my foreshadowing, yet somebody in their questionable judgment chose to mark my comment as SPAM; which is n'okay since it led to generating your followup comment of which the 2nd paragraph was useful elsewhere.
