[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] Cepasaccus:
To replace my ipad 2 I bought a Tab S5e LTE to run lineage because I am quite happy with my S10e running lineage. Unfortunately it is as always a fight for which I unfortunately need bit help.

So I want to install lineage 19.1 nightly. I managed to load vbmeta.tar and then the renamed and tared lineage-19.1-20221210-recovery-gts4lv.img using ODIN. Then I try to adb sideload and fail.

I get either

$ adb sideload lineage-19.1-20221210-nightly-gts4lv-signed.zip
Total xfer: 1.00x

or

$ adb sideload lineage-19.1-20221210-nightly-gts4lv-signed.zip
serving: 'lineage-19.1-20221210-nightly-gts4lv-signed.zip' (~47%) adb: failed to read command: Success

According to https://wiki.lineageos.org/devices/gts4lv/install this is not a sign of a problem:

Normally, adb will report Total xfer: 1.00x, but in some cases, even if the process succeeds the output will stop at 47% and report adb: failed to read command: Success. In some cases it will report adb: failed to read command: No error or adb: failed to read command: Undefined error: 0 which is also fine.

But I do get in the Recovery a

E:failed to verify whole-file signature
Update package verifytion took 43.0 s (result 1).
E:Signatue verification failed
E:error: 21
Install from ADB completed with status 2.
Installation aborted.

and the samsung ROM doesn't get overwritten.

The instructions say:

Note: Add-ons aren’t signed with LineageOS’s official key, and therefore when they are sideloaded, Lineage Recovery will present a screen that says Signature verification failed, this is expected, please click Continue.

But it really fails and I don't see any Continue which I could click. Do I have perhaps the wrong recovery? I see a lot of recoveries, which look differently.

I have not found a solution to this.

I assume the next issue I will have

if

I can solve this is Magisk. Apparently "Apply update from SD Card" is not good enough anymore and I will have to patch something. Is there maybe an easier root kit? I won't install the google stuff and therefore won't need the hiding features.
