ubuntu terminal notification: found module 'Cryptodome' but it is too old

[chrade]

Hi there, this is my first post 

On ubuntu 20.04, verified electrum 4.09 gpg signatures and installed it from python sources as per official instructions from https://electrum.org/#download.

There were no previous electrum installations on this system.

When i type electrum in the terminal, the gui software fires up saying Electrum 4.0.9 at the top,

but I also get the following notification in the terminal:

"W | crypto | found module 'Cryptodome' but it is too old: 3.6.1<3.7"

Is this something I should be worried about?

It shouldn't pose much of an issue or else your Electrum wouldn't have proceeded at all.

Electrum currently uses cryptography as a dependency as well and I think they use that by default and pycryptodome became optional quite some time ago. Cryptography is a mandatory dependency while cryptodomex is an optional one, it doesn't affect if your version is lower than the required as it's just included in their dependency checks.

You can update it if you want, pip install pycryptodomex.

I used the following command successfully.

Code:

python3 -m pip install -U pycryptodomex
Collecting pycryptodomex

     |████████████████████████████████| 13.7 MB 5.2 MB/s 
Installing collected packages: pycryptodomex
Successfully installed pycryptodomex-3.9.9

The

Code:

python3 -m

part, is from the instructions at https://electrum.org/#download

I also tried without the

Code:

-m

flag, but it wouldn't work.

Thanks a lot guys

Try replacing the pip with pip3?

Anyways, as said it wouldn't really matter because Electrum probably don't need it at all or else it would've been required to be installed as one of the dependencies and for which, it was dropped from the requirements some time ago[1].
