Electrum personal server is out of date quite a bit.

[Saltius]

I reinstalled it last night.

It requires a legacy wallet created in bitcoin-core to serve as an rpc bridge to get onboard the full node.
If the wallet is not a legacy one, then comes the "Only legacy wallets are supported by this command" things when EPS fails to start.

However legacy wallets can't be created in bitcoin-core v26 the latest version neitherby GUI nor commandline nowadays.
I need to add deprecatedrpc=create_bdb in bitcoin.conf at first, then manually create a legacy wallet through commandline.

This whole process above reminds me that EPS is out of date. Time to move on to other substitutions maybe.

Yes, that's a bit old based on their GitHub activity why not switch to other Electrum server?
There are 3 alternative options that I know ElectrumX, Electrs, and Fulcrum servers.

Heads-up, those other Electrum server implementations aren't as "lightweight" as EPS.
If you're looking for similar implementation, Sparrow wallet has a very similar approach to connect to Bitcoin Core but supports descriptor wallet.
That's if you're open to switch from Electrum to Sparrow.

In case someone is interested to merge EPS to Electrum,
Please consider replying to this issue (posted by the dev himself): Fix EPS and build it into Electrum #8142

Actually years ago I once tried ElectrumX before but my old laptop's pathetic hardware seems insufficient for it. Thus I turned to EPS then.

I may tried Electrs later. Thanks for your suggestion.

Yeah, the lightweight one I seek. But I notice that Sparrow wallet doesn't come with an android version while Electrum does.
Could I use an Electrum installed android phone to sign transactions generated by sparrow watch-only wallet?
If so, it may save me much time and efforts as I don't need to install linux deploy things on my old cellphones.

That's quite the setup, Android Electrum is your Air-Gap device?
But the answer is yes, both Electrum and Sparrow use "Partially Signed Bitcoin Transaction" (PSBT) export but Electrum is specific on its supported format.

Here's how to export an Electrum-compatible format:

• After creating the unsigned transaction in Sparrow; use the menu: "File->Save PSBT->To Clipboard->As Base64"
• Then transfer that copied text file to your phone through your preferred method.
• To import it to mobile Electrum, copy the base64 PSBT string, use "Send" then "Paste from clipboard".
• To export it after signing, use: "Share->Copy to Clipboard".
• Back to Sparrow, use the menu: "File->Open Transaction->From Text...", paste and broadcast the signed transaction.

You can also use: "Click File->Save PSBT->As Base64" to save it as a text file that you can transfer to your phone.
Open that txt file and copy the contents then do the last few steps above.

If you still care about performance or time to obtain transaction data, please read this benchmark first https://www.sparrowwallet.com/docs/server-performance.html. IMO Electrs and Fulctrum are best option, although each of them have different trade-off.
