Thanks for the reply Jackg.

That re-run of the installation certainly seems to have done something as I now have it running from the file in /.local/bin/.
Electrum directories present - installation appears complete

Thank you for the contribution and interest.

A bit more information..........................

I tried the option "Run without installing" on the Electrum web site - worked perfectly.

Then I ran install again.

sudo apt-get install python3-setuptools python3-pip
python3 -m pip install --user Electrum-3.3.8.tar.gz[fast]

I'm sure the python installation command is working correctly.
Problem seems to lie with the Electrum installation command as, amongst other things, the Electrum icon has still not re-appeared.

Hope this helps.

Hardware :- Acer Aspire 7740G laptop.         OS :- Ubuntu 19.04


Intention here is to have a fresh installation of Electrum on my laptop.
I cleared ALL references to Electrum from the Home directory and did a fresh system installation of Ubuntu 19.04

I did a fresh Electrum 3.3.8 installation from the website - no errors reported.

I noticed there was no Electrum icon, no Electrum 3.3.8 sub-directory and no .electrum sub directory.

I tried "/.local/bin/electrum" in terminal and got the reply :-  No such file or directory. (The file / directories ARE present)

No Electrum

I tried a re-install and got.................................

I found another "uninstall command line" and tried that......................................

Skipping electrum as it is not installed.

I am stumped as to why the 'fresh' installation did not work in the first place.

Anyone see where I'm going wrong ?

~/.local/bin/electrum

That was the answer - I just wasn't locating the executable.

Many thanks to you all for the assistance.

Thank you for your replies.

nc50lc - I have the wallet re-seed key. I re-installed Electrum - installation seemed to run perfectly but no icon when complete. Using terminal, the reply to command 'electrum' was once again, command not found !
TryNinja - Electrum is NOT present in usr/local/bin/ - the directory is actually empty.

Further help stili needed - thank you !

Newbie here...........

Last week, I had Electrum 3.3.4 running on Ubuntu 18.04 - ran flawlessly.
I updated Ubuntu to 19.04 - Electrum appears to have 'disappeared' !
Icon has gone - typing 'electrum' into Terminal produces reply "Command not found"
The Home/Electrum directory is present and, I presume, correct.
Can anyone help show me the correct way to re-connect with the wallet.

Many thanks,

Apologies to all who have contributed for the delay in replying.

Abdussamad - your moniker 'legendary' is well earned !!
I used the first of your command lines and a 3.3.8 window opened more or less immediately and, after several 'synchronizing' sessions, the content was present and correct.

Many thanks for your sterling help.

Semperlinux.

Tried your recommendation - completed with 'Electrum uninstalled'

Start icon disappeared - forgot to check /.electrum directory.
Installed 3.3.8 according to Electrum website - copy / paste terminal commands using PIP to install.
Install ran perfectly - /.Electrum directories present but no start icon. There is no /Electrum directory entries / structure present (I have this on my 3.3.8 laptop installation.
Tried command line start (electrum) - no joy.

Now I have no wallet at all. Help !?!

Hardware is Acer desktop running Ubuntu 18.04.2.

My old Electrum wallet would not synchronize so I did a backup, downloaded 3.3.8 and installed. Everything ran fine - no errors.
When I re-started the wallet, up came my old 2.5.4 version - obviously, still no sync.
Have tried several times - no luck.
Should I be deleting something in /.Electrum ?
