pycryptodome vs pycryptodomex, files 'exist in filesystem'

Trying to run system upgrades, I end up with a bunch of file conflicts  / file exists in filesystem.

...
error: failed to commit transaction (conflicting files)
python2-pycryptodomex: /usr/lib/python2.7/site-packages/Cryptodome exists in filesystem
python2-pycryptodomex: /usr/lib/python2.7/site-packages/Cryptodome/Cipher/AES.py exists in filesystem
... (many, many additional files))

Its strange because the error seems to be coming from the installation of pycryptodomex (as seen above), but that package doesn't appear to be installed, or provide anything.. so i'm not clear why its being pulled in

[kodiuser@kodiarch ~]$ sudo pacman -Qi python2-pycryptodomex

Meanwhile, all of the files i've checked are owned instead by pycryptodome instead

[kodiuser@kodiarch ~]$ sudo pacman -Qo  /usr/lib/python2.7/site-packages/Cryptodome/Cipher/AES.py
/usr/lib/python2.7/site-packages/Crypto/Cipher/AES.py is owned by python2-pycryptodome 3.9.0-1

Looks like kodi recently switched from pycryptodome to pycryptodomex, 
https://git.archlinux.org/svntogit/comm … 58face2a65

I do think you should create a bug report against python2-pycryptodomex .
python2-pycryptodomex should atleast conflict python2-pycryptodome  .
A feature request to publish a newspost or pre-upgrade message manual action is needed for this kodi upgrade also seems a good idea.

The simplest way to solve the issue is probably to remove every package related to kodi including python2-pycryptodome , then run pacman -Syu .
Once everything is uptodate again, run pacman -Syu kodi .

Some hints :
pacman -i / --info , -s / --search and -Q / --query never require sudo .

pacman -Sy foo is almost always a bad idea. Use pacman -S foo or pacman -Syu foo .


Multi-init booting with apg Openrc and systemd coexisting
Automounting : not needed, i prefer pmount
Aur helpers : makepkg + my own local repo === rarely need them

Re: pycryptodome vs pycryptodomex, files 'exist in filesystem'

$ sudo pacman -Qo  /usr/lib/python2.7/site-packages/Cryptodome/Cipher/AES.py
/usr/lib/python2.7/site-packages/Crypto/Cipher/AES.py is owned by python2-pycryptodome 3.9.0-1

This looks quite fishy. Have you symlinked /usr/lib/python2.7/site-packages/Cryptodome to /usr/lib/python2.7/site-packages/Crypto? The official python2-pycryptodome package doesn't install anything to /usr/lib/python2.7/site-packages/Cryptodome

Re: pycryptodome vs pycryptodomex, files 'exist in filesystem'

@arojas-
It appears I have; I'm not sure when, why, or how...

kodiuser@kodiarch ~]$ ls -l /usr/lib/python2.7/site-packages/Cryptodome
lrwxrwxrwx 1 root root 39 Jul 24 22:29 /usr/lib/python2.7/site-packages/Cryptodome -> /usr/lib/python2.7/site-packages/Crypto

@Lone_Wolf
Thanks for the info; Perhaps i'll get there tomorrow night.  Ahh yes, i remember now using -Sy causes issues in grabbing he newest version of packages that won't align with outer things installed, or something like that.

EDIT
I bet it was based on the comments as part of this plugin
https://github.com/asciidisco/plugin.vi … -292145025

I think we can close this thread;
