Hello to everyone on this forum.
I’m a newbie here with smartphones and trying to escape from GAFAs dictatorship.
When trying to install /e/ on S4 mini from an Ubuntu 14.04 host machine, I was at the very final step of the installation manual [https://doc.e.foundation/devices/serranoltexx/install], close to be done.
I was in recovery mode with TWRP on the phone, trying to sideload the /e/ .zip package, and Terminal showed “cannot read ‘sideload’”.
Any suggestion?

Hello, welcome in the community 
To sideload you have to :
- “apt install adb” on your Ubuntu
- In TWRP go to Advanced > Sideload > swipe to enter in sideload mode.
- then on Ubuntu go with the terminal where the file to sideload is and enter “adb sideload FileToSideload.zip”.
Hi and thanks a lot for your quick answer and help.
- adb was already installed on my Ubuntu,
- everything had been done in TWRP,
- my first mistake was that I hadn’t gone with terminal where the file was located, but had directly entered “adb sideload /path/to/filetosideload.zip”, which I thought was the same.
Then I tried to do it the right way, but still with no success (“protocol error”).
At this point, I realized that TWRP had sent a notice showing that I needed adb version 1.0.32 or newer, as mine was version 1.0.31. I don’t know whether further versions of Ubuntu (mine is 14.04LTS) can have newer version of adb, but all my efforts to upgrade my adb with regular repositories proved unsuccessful.
Though, I could find a solution at this link:
https://askubuntu.com/questions/602129/how-to-update-or-re-install-the-newest-version-of-adb
adb version
Android Debug Bridge version 1.0.31
wget -O - https://skia.googlesource.com/skia/+archive/cd048d18e0b81338c1a04b9749a00444597df394/platform_tools/android/bin/linux.tar.gz | tar -zxvf - adb
sudo mv adb /usr/bin/adb
sudo chmod +x /usr/bin/adb
adb version
Android Debug Bridge version 1.0.32
And I eventually could go through the installation of /e/ on my S4 mini.
Nevertheless, thanks again for the time you spent on my problem!
