Pending force close

[Rothschildiuk]

After a recent failed update of Umbrel to version 1.0.0, I was forced to install the old version and re-sync Timechain and LND, of course, it forced closed all my channels. 4 of 6 channels closed successfully, but 2 channels are pending.

The closing fee is set at about 1.0 sat/vB, which is very low.
Can anyone help me accelerate this process?

I tried to use bumpclosefee lncli wallet bumpclosefee --sat_per_vbyte 40 2aeb70245d71dae332321a01317753220695ef125eaa905d52364b2601fea224:0 but unsuccessful, with response channel not found.

Currently LND is not able to do this by itself, but it's on the roadmap: #8280

But you can use chantools as describe in the issue chantools pullanchor which will use the anchor to accelerate the Commitment Transaction.

[Rothschildiuk]

Since the channels that cannot be closed are large nodes (Kraken and ACINQ), maybe their owners will speed up the transaction and I won't have to do anything? I think it makes sense to wait a week... If not, could you please provide a link to a tutorial or instruction on how to do this because I can't find it.

Yes might work that your channel peers bump the fee.

Closing in favour of #8280
