I did try to update to the latest version of electrum i.e. 2.9.3 on my linux PC.

I did this successfully following this procedure.
sudo apt-get install python-qt4 python-pip
wget https://download.electrum.org/2.9.3/Electrum-2.9.3.tar.gz
tar -xvf Electrum-2.9.3.tar.gz
cd Electrum-2.9.3

I have since also done this successfully with a litecoin electrum wallet.
However, although I did backup my wallet files from the repo version, from my original wallet with the btc balance,  I have yet to uninstalled it. I feared to do this, since I tried to sweep the wallet into a new wallet version a couple of times unsuccessfully ('no inputs' was a message that came up).

At least the original version is showing my wallet balance.

I have not found instructions anywhere to uninstall either of the btc electrum wallet packages that are shown in the software manager. When I used the package manager it seems to just freeze and I get nowhere.

I believe I may have installed pip2 on a previous occasion. I shall investigate this. Perhaps there are terminal commands to uninstall the repo version. I shall look again.


Your suggestion certainly sounds like a good solution. Thank you
