help with "bumpfee" at the comman line

[almqq]

Hi, I am trying to increase the fee of a transaction I created (also at the command line)

I tried this:

$ electrum bumpfee 39e05fa9a63d650c5476e02d79acd3ede9e4813cdb381b2c9087fff25c226728 18

but got this error message:

attempt to read past end of buffer

How can I progress?

Thanks

The error you mentioned actually fixed in version 3.2.0, which was years back.

Check your Electrum version, if it's not ver 4.4.6 then update it to the latest version from their official site: https://electrum.org/#download

The updated version most likely will resolve this error.

Hi
I am using version 4.4.6, installed about a couple of weeks ago
(on an linux machine, Ubuntu 22.04.3 LTS)
Everything else (all other command line options) seem to work fine
Any other ideas?

The error you mentioned actually fixed in version 3.2.0, which was years back.

According to this bug reports it also comes up on newer version no report yet on the most recent version but other version like 4.1.5 also have this bug.

@OP
Did you get the error message after you enter the command line? Or does it also show up on the Electrum GUI?

If the error came from the most recent version I suggest report this to the Electrum issue page and then let the developer release a fixed version.

If you have a backup seed I suggest try to downgrade Electrum to 4.4.5 or lower and update here if it fixes your issue.

Yes, happens at the command line, I'm not using the GUI so I don't know if it happens there as well
I have left a bug report at https://github.com/spesmilo/electrum/issues/8603

I'll try a 4.4.5 instance and report back

I tried it with the current master build from GitHub (source) and it also result with the same error, seems like a bug.
Here's the log:

Code:

I saw that you just made a new issue in GitHub (seconds ago) regarding this issue: link

Hi
I see it failed for you on version 4.4.4
Which is the last version it is know to work?

I'm about to edit it since I've provided logs from my previous test session.
But given this reply, I think editing it isn't necessary anymore.

Both v4.4.4, v4.4.6 and master branch results are the same so it's not yet fixed.

At the moment my immediate concern is to get the "bumpfee" to work, somehow
I can download and install any previous version of electrum (on another machine), which one do you think will be able do the bumpfee?
Any other ideas?

If I am not wrong I used the bump fee on my Android 4.4.5 with no issues, so if you can import the wallet or that address to an Android Electrum and click the transaction there you can see the bump fee at the bottom.

This worked! thanks!

I will keep an eye on any progress with my bug report
https://github.com/spesmilo/electrum/issues/8603

Thank you all for all your help

Try to combine commands:

$ electrum gettransaction 39e05fa9a63d650c5476e02d79acd3ede9e4813cdb381b2c9087fff25c226728 | electrum bumpfee - 18
