You just looked at mempool.space and saw empty blocks and decided to open a shiny new channel to a peer with promise at 1 sat/vB. But as soon as your transaction is sent, you look at mempool.space and now there are 6 blocks full and fees are at 23 sat/vB. We aren't bumping the fee for a channel open, we are going to increase the value of mining the "change" your wallet was receiving back so that miners will be enticed to bite and include your channel open as well.
In terminal type: lncli pendingchannels Find the channel_point and copy everything up to the : paste those digits into blockstream.info Look at the outputs and see which one is your change (usually 1 or 0) Let's make the change look tasty. If the change is #0 type:
lncli wallet bumpfee (channelpoint number from step3, no parenthesis):0 --sat_per_byte 50 Make the sat_per_byte double the going rate on mempool.space That's the kind of milkshake that brings the miners to the yard.
Once you press enter you will not see fireworks. It will just be a blank line. You can go lookup the transaction on blockstream by clicking on the change output from step 5.
Cut and paste this into a txt file and save on your desktop for future use.

For a channel open, you actually do not bump the fee. Fee bumping means replacing the old transaction with a new one with a higher fee. Since channel open renegotiation is not built in to the protocol, you will have to use the CPFP "trick", where you spend the bitcoin (change) from your unconfirmed (channel open) transaction.

That is MUCH more concise and well put together than the reddit posts I figured it out from and a GitHub issue, thank you!
