Python netmiko failing to install - problem with pynacl

Question

Hope you can help. I am a novice in respect of Ubuntu so apologies in advance.

I am running Ubuntu 16.04 and am trying to install netmiko in python3.5.2

I am hitting a problem with pynacl which is causing the install to fail. The type of error messages I am getting are as follows:

/tmp/pip-install-d4reycz5/pynacl/src/libsodium/src/libsodium/crypto_hash/sha256/cp/hash_sha256_cp.c: In function 'crypto_hash_sha256.constprop': /tmp/pip-install-d4reycz5/pynacl/src/libsodium/src/libsodium/crypto_hash/sha256/cp/hash_sha256_cp.c:205:31: warning: iteration 64 invokes undefined behavior [-Waggressive-loop-optimizations] state->buf[r + i] = in[i]; ^ /tmp/pip-install-d4reycz5/pynacl/src/libsodium/src/libsodium/crypto_hash/sha256/cp/hash_sha256_cp.c:204:9: note: containing loop for (i = 0; i < inlen; i++) { ^

I believe I have all the necessary modules eg libsodium etc. Look forward to hearing from you.

I think I have found the solution. It appears that Netmiko is only support on Python3.6 and above.

Have installed Python3.8.5 and it appears to be working.
