Title: Ubuntu 20.04 Bitcoin-Core Snap: Permission for external disk Post by: djoser on May 15, 2020, 02:01:55 PM Hello.
I recently installed Ubuntu 20.04 and installed Bitcoin-Core 0.19.1 from the Snap-Store. The Blockchain is stored on an external drive. When i open the application i'm asked for the directory of the blockchain. Problem is that the application seems to lack permission to write to the external disk. How can i give permission to the application? Thanks and regards djoser Title: Re: Ubuntu 20.04 Bitcoin-Core Snap: Permission for external disk Post by: LoyceV on May 15, 2020, 02:43:09 PM Problem is that the application seems to lack permission to write to the external disk. Is it an application problem or a user/permissions problem? To test: can you write to the external disk using another program?Quote How can i give permission to the application? My guess is you'll just need to change folder permissions, see for instance Change folder permissions and ownership (https://askubuntu.com/questions/6723/change-folder-permissions-and-ownership).Title: Re: Ubuntu 20.04 Bitcoin-Core Snap: Permission for external disk Post by: djoser on May 15, 2020, 02:50:43 PM Is it an application problem or a user/permissions problem? To test: can you write to the external disk using another program? It seems to be an application problem, because everything else (like writing/copying files to the drive) works perfectly. My guess is you'll just need to change folder permissions, see for instance Change folder permissions and ownership (https://askubuntu.com/questions/6723/change-folder-permissions-and-ownership). I think i need to give permissions to write to external usb devices directly to the application. I know that this is possible, i just don't know what the specific command console command is.

I'm guessing the drive is fully kounted/findable in /media/drivename to you and you see able to write to it?

I know that this is possible, i just don't know what the specific command console command is. If it runs as the same user, it has inherited the same permissions already.Can you check (or post) this file: Code: ~/.bitcoin/debug.log Title: Re: Ubuntu 20.04 Bitcoin-Core Snap: Permission for external disk Post by: djoser on May 15, 2020, 03:10:17 PM Sorry, no such file, because "~/.bitcoin" does not exist. It's a snap.
BTW: I hate those snaps anyway >:( The application shows the error "It could not be written to directory 'media/....' Check permissions."

But i wanted to give it a shot.
There must be a solution for this... Title: Re: Ubuntu 20.04 Bitcoin-Core Snap: Permission for external disk Post by: LoyceV on May 15, 2020, 03:42:54 PM There must be a solution for this... I've never used "snap" (and until today didn't know it exists), so as a guess, read How to get access to USB-storage from the application installed as Snap?

Unfortunately snap "bitcoin-core" has no plug named "removable-media". I think unless the blockchain is mounted in root directory the snap is useless :( Title: Re: Ubuntu 20.04 Bitcoin-Core Snap: Permission for external disk Post by: Abdussamad on May 16, 2020, 07:26:54 AM why are you using a third party snap? it's unsafe. you should download bitcoin core from bitcoincore.org. untar that download and run bitcoin-qt from the bin directory. it's very easy.
Title: Re: Ubuntu 20.04 Bitcoin-Core Snap: Permission for external disk Post by: djoser on May 16, 2020, 11:16:00 AM This is the official core-client from the official ubuntu repository.
So there should be no security issue!? Since my problem from the first post seem to be unsolveable, i'm forced to use the tgz-packed client anyway. BTW: The snap-application is also shown as an option on bitcoin.org!! |
