Manual install fails

[krystof018]

When I run opkg update && opkg install swap-utils zram-swap I get this as output:

You can skip the zram-swap since there’s no noticable performance improvement. Is there any reason to why you are following the manual steps?

[krystof018]

I was trying manual steps because automatic install fails to install some packages and octoprint is then not working.

Collected errors:
 * opkg_install_cmd: Cannot install package python3-psutil.
 * pkg_hash_check_unresolved: cannot find dependency python3-pycparser for python3-cffi
 * pkg_hash_fetch_best_installation_candidate: Packages for python3-cffi found, but incompatible with the architectures configured

Are you on latest openwrt firmware?

I was trying manual steps because automatic install fails to install some packages and octoprint is then not working.

Collected errors:

I'm also encountering a similar issue with the automatic installation.
Before this, I encountered an issue with urllib3 like described in #36.
The code below resolved the urllib3 problem:

pip uninstall urllib3
pip install -Iv urllib3==1.26.11
opkg update && opkg install python3-requests
cd /root/OctoPrint-1.8.4
python setup.py install

However, setup.py fails with:

In an attempt to resolve the cffi issue, I tried the following:

opkg update && opkg install python3-cffi

But this returns the following error:

Collected errors:
 * pkg_hash_check_unresolved: cannot find dependency python3-pycparser for python3-cffi
 * pkg_hash_fetch_best_installation_candidate: Packages for python3-cffi found, but incompatible with the architectures configured
 * opkg_install_cmd: Cannot install package python3-cffi.

I noticed that pycparser isn't a part of all the OpenWrt packages.
@ihrapsa, I'm guessing that's where your question regarding firmware version might come from.

My version: OpenWrt SNAPSHOT, r20027-586c2426d9 (from Release page)

When I last worked on this, python3-pycparser was missing from:
https://downloads.openwrt.org/snapshots/packages/mipsel_24kc/packages/

Today I was able to run the command below and install python3-cffi without any problems, since it seems the dependent python3-pycparser package mysteriously reappeared. I guess that's the danger of these snapshot builds...

opkg update && opkg install python3-cffi

I then ran the following command and Octoprint is running sucessfully after a poweroff.

cd /root/OctoPrint-1.8.4
python setup.py install
