Oh, well that sucks, but it doesn't really help me, I wish a new real competitor entered the E-Ink ereader world.

Do try what I described earlier: if it doesn't crash with WiFi on, that's a pretty strong hint that it's the same issue(s) .

But you stated that the wifi would fix the known issue.

I appreciate the help, but it's annoying.

When in Nickle and I upload a book it via usb using calibre it usually hangs when rebooting and updating it's database, with a hard reset it's fine in Nickel, but in KO Reader there will always be missing GUI elements that I need to do a dev to stable update to get it fixed. The desired new book does get added too, so it's merely annoying.

I have added the required line to ignore all the ui elements that Nickel picks up, but it still now has those elements in it's database, is there a quick way to remove those from it's database?

I have been able to successfully add books via Wifi with Calibre wirelessly, I'm not sure if that answers your question.

My issue with wirelessly adding books is that they go into the wrong default folder and I'm not sure how to change that in KO Reader, is there an easy way to tell KO Reader the default folder for wifi received books?

Ideally, as a wish, KOReader would completely separate its "data" files from its "system" files, so even as things change, all you would have to do is backup one folder and it would (almost always) survive future updates (like the recent defaults.custom.lua change that I only found out about after restoring my old backup and losing my defaults settings). This would mean moving settings.reader.lua, defaults.custom.lua, styletweaks, custom fonts, history, screenshots, patches to the existing "settings" folder, so we can just back up that "settings" folder. The SDR files are fine where they are among the books imo.

My backup script as of today, mostly based on @NiLuJe's script above but updated for the latest KOReader. I run it when the Kindle/Kobo is connected over USB to a Mac. The LIBRARY_ROOT, KOREADER_DIR, and TMPFS_PATH lines are for Kindle right now, but the Kobo alternative is commented out, so you can switch to that version if you use Kobo. Or adapt these 3 paths to whatever computer OS and ereader you have.

# Catch failures
set -e
set -o pipefail

# Root directory of the Library
LIBRARY_ROOT="/Volumes/Kindle/books"
#LIBRARY_ROOT="/Volumes/KOBOeReader/.books"

# KOReader install directory
KOREADER_DIR="/Volumes/Kindle/koreader"
#KOREADER_DIR="/Volumes/KOBOeReader/.adds/koreader"

# We'll work in a tmpfs
cd ~/Desktop
TMPFS_PATH="kindle-koreader-$(date +%F)"
#TMPFS_PATH="kobo-koreader-$(date +%F)"
mkdir -p "${TMPFS_PATH}"
cd "${TMPFS_PATH}"

# Start by collecting the list of sidecar directories we'll want to backup...
echo "* Computing sidecar folders list . . ."
find "${LIBRARY_ROOT}" -type d -name '*.sdr' -print0 > sidecar_list
echo

# Then we want to backup KOReader's settings
echo "* Computing KOReader settings list . . ."
KO_FILES="cache/calibre/libraries.lua cache/calibre/books.dat defaults.custom.lua history.lua settings.reader.lua"
KO_FOLDERS="clipboard history settings styletweaks patches screenshots fonts/custom"
# Allow skipping dictionaries...
if [ "$#" -ge 1 ] ; then
KO_DICT_FOLDERS=""
else
KO_DICT_FOLDERS="data/dict data/tessdata"
fi
for path in ${KO_FILES} ${KO_FOLDERS} ${KO_DICT_FOLDERS} ; do
echo -en "${KOREADER_DIR}/${path}\0" >> koreader_list
done
echo

# Compute the final list
cat sidecar_list koreader_list > input_file_list

# Tar it up...
BACKUP_FILE="${TMPFS_PATH}.tar.gz"
echo "* Creating tarball . . ."
bsdtar -cf "${BACKUP_FILE}" --zstd -T input_file_list --null --exclude '*.old' --exclude '*.old_dom*' --exclude '*.old.[0-9]' || true
echo

# Remove lists
rm -f sidecar_list koreader_list input_file_list

# Move tar to Desktop
mv "${BACKUP_FILE}" ~/Desktop/

# Remove temp folder
cd ~/Desktop
rm -rf "${TMPFS_PATH}"

# We're done! Don't actually unmount the tmpfs just yet... ;o)
echo "* Done, backup stored in ~/Desktop/${BACKUP_FILE}"

Which was entirely my point: we won't know if it's actually the same issue until you try.

Remember, I have *never* had any of the affected device, so I'm just making extremely shaky assumptions. If everyone gives up without trying stuff, we'll never get anything done on that front.

It's unclear to me whether this is actually a Nickel DB issue or simply a good old filesystem corruption one .

If the ignore directives takes, nothing makes it to the DB *at all*, so I'd be inclined to vote for "FS corruption" .

(As for why KOReader and not Nickel: KOReader lives in the onboard, USBMS partition: that's FAT32, which is not journalled, and notoriously terrible at recovering from system faults. Nickel, on the other hand, lives in the rootfs, which uses a sane journalled Linux fs).

@mbrisco: I don't actually know why we never moved everything to settings (I suspect because the folder came later than the reader.settings stuff), but it is mildly annoying indeed ;p.

You can look for style tweaks in the user guide: http://koreader.rocks/koreader-user-guide.pdf

Things to check are class “p” and its margin properties, as well as class “empty-line”.
