balena etcher was able to clone sd-card to a bigger sized one with no issues;
(maybe the read-command functions only with drives that have no-multi-partition, not with ones like contains libreelec)

it seems picky with copied over .iso?
just copied over from NAS latest ubuntu 26.04 and got error when using the isoimagewriter.

If by picky you mean verifying you have a proper copy of the .iso then yeah I guess so. To get by that download 256sum file into the same directory as the .iso as it tells you to do or create it with the sha256sum program.

Are you using Daedalus or an earlier version of Devuan?

it has been ably written from daedalus box;
however , could now install it (ubuntu25.10)

if could vote, would still +1 for usbimager; but the mintstick is perfectly fine atm since can use;
but who will find it in the repos?

sudo apt install isoimagewriter

E: Unable to locate package isoimagewriter

+1 still for USBimager, in soem regard; but it lacks the format option, is therefore not fully complete.
(but can also read images for backup)

The USBImager does not need any format option. Formatting a drive that gets overwritten with an iso does not make any sense.

turned out did it wrong; was passing along the path of iso and expecting it is already set-up for ; but just found out that i just have to "select" the ISO once more and then the stick becomes visible;

so it seems even GUI-tooling is not always "foolproof" for newbies alike;

could the called "solved" since the item does include the two sought-for functionalities in a rather handy way, although it has some "entry" barriers (format usb need to called from terminal)

thanksalot.

however, it would not recognize the usb-stick for when writing iso, however it would recognize it when trying to format usb-stick?

Wow, never had that problem with it, weird. It's no exaggeration to say i've used it 1000 times in the last year, and never once had a problem. In fact I made a helper app to go with it, to add a fat32 data partition to the stick after installing the iso.

Possibly you're missing a dependency or maybe even a recommend? Let me know how it turns out please!

sudo apt install isoimagewriter

thanks @greenjeans,

mintstick is such a program as i was looking for!

Mintstick is what you seek my friend, it's in the repo, it's an awesome utility. Refracta2usb if you want to do more complex things like multi-boot and persistence.

There is also isoimagewriter for creating bootable USB flash drives from hybrid ISO files.

both seem very nice, innocuous,  please test to judge if its suitable.

tried both .deb and they would install on devuan 6 , and function , and needed to include some more packages.

it would be nice if they could be installed via devuan repository.

it is good practice to offer help via GUI for less tech-savy users and newbies.

always found it difficult to use the inbuilt-tools for making bootable usb-sticks.
(maybe with excaption of linux-mint, but digress)

thanks.

it is harder to use "mkusb" program on Devuan/Debian nowadys

mkusb is an Ubuntu specific tool, so that's not particularly surprising.

The closest you will get to a "universal" bootable-media tool is ventoy, which should run fine on Devuan.

both provide .deb packages which will very likely work on Devuan. Have you tried them?

mkfs.fat -F32 /dev/[whatever]

Why on earth do we need a GUI for this?
Similarly, for writing single hybrid images to removable media, dd or cp work just as well as they always have.

i am kindly requesting including of 1 or 2 package into Devuan
since it is harder to use "mkusb" program on Devuan/Debian nowadys;

have tried several program and they seem function well, and it seems such a program is missing in Devuan?

it is very handy and function without friction;

one is called "USBImager"   - another which could be used to format SDcard or USB to standard FAT32 aswell, is called "ddCopy"

thank you very much.
