liana-gui : Panic when creating new wallet at step 5/5 'finalize installation'

[cc1cc1cc1]

Running under Ubuntu 22.10 with Mate 1.26.0, linux kernel 5.19.0-26 bitcoincore installed using snap

bitcoin.conf: rpcallowip=127.0.0.1 server=1

cookie path is ok

I got this output instantly after pressing "finalize installaton" buton at step 5/5:

Thank you for your report. We could document this better but it is an issue on your end: the bitcoind process isn't able to create a wallet within the Liana data directory (~/.liana/bitcoin as your example for mainnet). It is most probably not writable by the user your run bitcoind as, as suggested by the output of ls -al you pasted.

[cc1cc1cc1]

i got that, but the .liana folder is made by liana, so the soft itself define access right, is'nt it?

[darosior]

Yes, the data directory is created with no permissions for the group and others: https://github.com/wizardsardine/liana/blob/80fb0ecb01f65c15782f215fdda9bc99ad6c78d2/src/lib.rs#L136-L148

Are you running bitcoind as another user? If so there are two ways we could support this:

• Allow to configure the permissions the data directory is created with
• Allow to use a bitcoind watchonly wallet from outside Liana's data directory

I think the second one makes more sense as i can imagine it to be useful in other situations as well. What do you think?

cc @edouardparis if you have any suggestion too.

I don't use Snap, but a quick search seems like it would install Core as root. Liana would be installed as the user. Might be that, but i'm absolutely not knowledgeable with Snap.

[cc1cc1cc1]

cc1@cc1:~$ ps -aux | grep bitcoin
cc1        12570 51.3  4.9 5658348 790240 ?      SLl  21:28   3:21 bitcoin-qt

so i'm running bitcoin-qt (not bitcoind) by same user than liana so i think problem not from there

but when i check for bitcoind and bitcoin-cli:

cc1@cc1:~$ bitcoind --version
bitcoind: command not found

cc1@cc1:~$ bitcoin-cli --version
bitcoin-cli: command not found

then i found them here:

cc1@cc1:~$ locate bitcoind | grep snap
/snap/bitcoin-core/120/bin/bitcoind

cc1@cc1:~$ locate bitcoin-cli | grep snap
/snap/bitcoin-core/120/bin/bitcoin-cli

[cc1cc1cc1]

just try that:

sudo ln -s /snap/bitcoin-core/120/bin/bitcoin-cli /usr/bin/bitcoin-cli
sudo ln -s /snap/bitcoin-core/120/bin/bitcoind /usr/bin/bitcoind

but still have the same issue

[cc1cc1cc1]

running bitcoind instead of bitcoin-qt seems solve issue but....

new issue following:

should i open new issue for this one or they are linked?

[darosior]

It's very surprising that running bitcoind in place of bitcoin-qt solved the issue. If the lack of RPC server (by default when running bitcoin-qt) was the issue we'd fail earlier in the process.

should i open new issue for this one or they are linked?

I've opened #284 to track this.

[cc1cc1cc1]

yes very surprising because i can connect to rpc using python bitcoinrpc package with this setup... i'll double check with a fresh install of bitcoin-core from sources

[cc1cc1cc1]

just try with bitcoin-qt build from source, works fine then reinstall from snap, seems they update version, now it is fine, working with bitcoin-qt from snap also
