Electrum-LTC is a simple, but powerful Litecoin wallet. It has pretty user interface and is quite easy to use.

From my previous Linux distribution i have /home/user/.electrum-ltc/ directory containing my wallet files. The Electrum LTC was installed using AUR on it, but on current Debian, i have selected an AppImage format.

So after downloading .AppImage file from https://electrum-ltc.org/ (wget pathhere)
I added execute permission (chmod +x filename)
and ran it (./filename)
I was able to set to import wallet by adding its address. It created read only wallet. Then i went to a main menu and selected to import/open wallet and selected my wallet that i had saved from earlier Linux distribution (saved in /home/user/.electrum-ltc/ as mentioned)

and it worked.
