Unable to find a way to RBF a transaction

[Javihache]

As a continuation of my previous issue, I tried to follow this guide: https://docs.corelightning.org/docs/faq#how-to-forget-about-a-channel

I swept the funds but forgot to set a feerate=urgent as I just copied and pasted the command. Now the transaction with 2sats/vB is of course stuck in the mempool.

To my surprise there's no way to RBF with a simple "bumpfee" like bitcoin-cli operates. Also there's no way I can find to create a raw transaction to at least spend a UTXO and replace the transaction. I can't imagine this is a problem nobody ever found and that has no solution.

How do you go about bumping a fee with Core Lightning?

Thanks in advance again.

I have been breaking my head with this problem for hours. It seems it's absolutely impossible to accelerate a transaction. ChatGPT can't help and there's no information anywhere in the documentation about this topic.

Is my only option to pay a lot of money on mempool.space to accelerate the transaction? really?

Same issue... Not sure how to get the transaction's PSBT so I can provide it as an argument to lightning-cli openchannel_bump... @Javihache did you end up finding a solution to this?

This helped me but i needed to change "script type" to native segwit: https://github.com/ElementsProject/lightning/issues/6666#issuecomment-1859271437

But please CLN developers add a simple "bumpfee" command where you can input the txid and a new fee in sat / vByte or another simple solution for this.
